What is stainless steel material？

Generally speaking, stainless steel is not easy to rust steel, in fact a part of stainless steel, both rust, and acid resistance (corrosion resistance). The stainability and corrosion resistance of stainless steel are due to the formation of chrome-rich oxide film (passivation film) on its surface. This rust resistance and corrosion resistance are relative. The test SHOWS THAT THE CORROSION RESISTANCE OF STEEL in the atmosphere, water and other weak media and nitric acid and other oxidizing media, its corrosion resistance increases with the increase of chromium content in steel, when the chromium content reaches a certain percentage, the corrosion resistance of steel changes, namely from easy to rust to not easy to rust, from corrosion resistance to corrosion resistance.

stainless steel pipe

Stainless steel material: stainless steel belt, stainless steel rod, stainless steel plate, stainless steel line, stainless steel pipe, product brand :SUS310S, 309S, 316L, 316, 316Si, 317, 304, 304L, 309, 305, 31403, 321, 301, 202, 201, etc.; Stainless steel provides satisfactory corrosion resistance for a wide range of industrial applications. According to the use of experience, in addition to mechanical failure, corrosion of stainless steel is mainly shown in: a serious form of corrosion of stainless steel is local corrosion (i.e. stress corrosion cracking, pitting corrosion, intergranular corrosion, corrosion fatigue and crevice corrosion). The failure cases caused by local corrosion accounted for almost half of the failure cases. In fact, many failure accidents can be avoided by reasonable material selection.

Stainless steel with its beautiful appearance, corrosion resistance, not easy to damage the advantages, more and more people love. POTS AND pans, city sculpture, building, decorate a bedroom to use stainless steel more and more. The other day, I saw a customer with a magnet on stainless steel utensils when he was buying stainless steel kitchenware. I asked him why he was using magnets. He said that the magnet on the stainless iron, not on the stainless steel, stainless steel is not magnetic. It seems that people's understanding of stainless steel and misunderstanding.

Iron and steel are distinguished by the amount of carbon they contain. An iron-carbon alloy with a carbon content of less than 2% is steel, and an iron-carbon alloy with a carbon content of more than 2% is called iron. Steel is widely used because of its toughness, elasticity and rigidity. Life is exposed to steel, but people call it different. For stainless steel, regardless of magnet on or not, as long as in line with its quality standards, are stainless steel. Therefore, from the point of view of metallurgy, there is no such thing as stainless iron. The main anti-corrosion element of stainless steel is chromium. Steel with a chromium content of more than 10.5% will not rust easily. When smelting, the alloy element added is different, and there is a magnet suction and not on the difference. Stainless steel is generally divided according to the structure of the organization, can be divided into austenite, ferrite, martensite and other categories. If you add different proportions of chromium nickel to the molten steel, the austenitic steel is not magnet on the stainless steel; If added to the molten steel chromium and a small amount of nickel (or do not add nickel), the steel is magnet on the stainless steel, also known as ferritic stainless steel; The main alloying elements of martensitic stainless steel are chromium, iron and carbon. There are more than 100 kinds of stainless steel because of the different amount of alloy. In addition to austenitic stainless steel magnet not on, ferrite, martensitic stainless steel are magnetic.

Nickel is a rare element in the world and the price is relatively expensive. Therefore, the price of stainless steel with high nickel content is also higher on the market, and the magnet is not attracted. In fact, there is a stainless steel magnet is not on. That's stainless steel with high manganese and low nickel or no nickel. The market price of this stainless steel is more than 1000 yuan per ton lower than the stainless steel with high nickel content. Some dealers are using people "good stainless steel magnets are not on" misunderstanding, cheat consumers, the price is as expensive as high nickel stainless steel.

There are more than 100 kinds of stainless steel, characteristics and functions are not the same. Generally do decoration, landscape, sculpture selection of austenitic stainless steel. Because of the low thermal conductivity of austenitic stainless steel, it is not appropriate to use it as a kettle, wok, rice cooker, will use a lot of energy, but also extend the cooking time. Using ferritic stainless steel for frying pan, rice cooker, not only has excellent corrosion resistance, and its thermal conductivity than austenitic stainless steel nearly half. The bucket inside washing machine, water heater, dish basin, should choose ferritic stainless steel as long as the vessel that contacts with water. Some people complain that stainless steel tool is not fast, this is because the wrong choice of stainless steel. Austenitic stainless steel can not be hardened, not suitable for cutting tools, cutting tools. The tool made of martensitic stainless steel can change the hardness of stainless steel by heat treatment, such as quenching and tempering.

Stainless steel plate is generally the general term of stainless steel plate and acid-resistant steel plate

Stainless steel plate is generally the general term of stainless steel plate and acid-resistant steel plate, since the beginning of this century, to now has more than 90 years of history. Its surface smooth, high plasticity, toughness and mechanical strength, acid, alkaline gas, solution and other media corrosion. It is a kind of alloy steel that is not easy to rust, but it is not absolutely rust free. Stainless steel plate refers to the air, steam and water and other weak medium corrosion steel plate, and acid resistance steel plate is acid, alkali, salt and other chemical corrosion medium corrosion steel plate. Stainless steel plate has high temperature oxidation resistance, however, the oxidation rate will be affected by the exposure environment and product form and other inherent factors.

[krystal-liu-888]

Stainless Steel (Stainless Steel) according to the definition of GB/T20878-2007 is stainless, corrosion resistance as the main characteristics, and chromium content of at least 10.5%, the maximum carbon content is not more than 1.2% of steel.

stainless steel plate

Stainless Steel (Stainless Steel) is the abbreviation of stainless acid steel, air, steam, water and other weak corrosion medium or stainless steel called stainless steel; And the chemical corrosion resistant medium (acid, alkali, salt and other chemical corrosion) corrosion of steel called acid steel.

stainless steel sheet

Due to the difference in chemical composition and make their corrosion resistance is different, ordinary stainless steel is generally not resistant to chemical medium corrosion, and acid resistant steel is generally stainless. The word "stainless steel" does not simply refer to a kind of stainless steel, but represents more than one hundred kinds of industrial stainless steel, the development of each stainless steel in its specific application field has good performance. The key to success is first to find out the purpose, and then to determine the right type of steel. There are usually only six types of steel related to construction applications. They all contain 17 to 22% chromium, and the better steels also contain nickel. The addition of molybdenum can further improve the atmospheric corrosion, especially the corrosion resistance of chloride-containing atmosphere.

[krystal-liu-888]

What are the main types of stainless steel?

Stainless steel is often divided into martensitic steel, ferrite steel, austenitic steel, austenite-ferrite (duplex) stainless steel and precipitation hardening stainless steel. In addition, can be divided into: chromium stainless steel, chromium nickel stainless steel and chromium manganese nitrogen stainless steel. Also used for pressure vessels with special stainless steel "GB24511_2009_ pressure equipment with stainless steel plate and steel belt".

Containing chromium 15% ~ 30%. Its corrosion resistance, toughness and weldability improve with the increase of chromium content, and its chloride stress corrosion resistance is better than other kinds of stainless steel, which belong to this category of Crl7, Cr17Mo2Ti, Cr25, Cr25Mo3Ti, Cr28 and so on. Ferritic stainless steel because of high chromium content, corrosion resistance and oxidation resistance are relatively good, but the mechanical properties and process performance is poor, mostly used for the force is not acid resistant structure and use as oxidation resistance steel. This kind of steel can resist the corrosion of atmosphere, nitric acid and brine solution, and has the characteristics of high temperature oxidation resistance, small coefficient of thermal expansion, etc. It is used for nitric acid and food factory equipment, and can also be made to work at high temperature parts, such as gas turbine parts.

Chromium is more than 18%, but also contains about 8% nickel and a small amount of molybdenum, titanium, nitrogen and other elements. Good comprehensive performance, can withstand a variety of media corrosion. The common grades of austenitic stainless steel are 1Cr18Ni9, 0Cr19Ni9 and so on. 0 cr19ni9 steel Wc< 0.08%, marked as "0" in steel. This type of steel contains a large amount of Ni and Cr, which makes the steel appear as austenite at room temperature. This kind of steel has good plasticity and toughness, weldability and corrosion resistance and non-magnetic or weak magnetic, the corrosion resistance in oxidizing and reducing medium are good, used to make acid equipment, such as corrosion resistant containers and equipment lining, pipelines, nitric acid resistant equipment parts, etc., also can be used as the main body of watches and clocks jewelry stainless steel material. Austenitic stainless steel is generally treated with solid solution, that is, the steel is heated to 1050 ~ 1150℃, and then water or air cooled to obtain a single-phase austenitic structure.

It has the advantages of austenite and ferritic stainless steel, and has superplasticity. Stainless steel with austenitic and ferritic structures of about half each. In the case of low carbon content, chromium (Cr) content in 18%~28%, nickel (Ni) content in 3%~10%. Some steels also contain Mo, Cu, Si, Nb, Ti, N and other alloying elements. This kind of steel has the characteristics of austenite and ferritic stainless steel, compared with ferritic, higher plasticity, toughness, no room temperature brittleness, intergranular corrosion resistance and welding performance are significantly improved, but also maintain the 475℃ brittleness of ferritic stainless steel and high thermal conductivity, with superplasticity and other characteristics. Compared with austenitic stainless steel, its strength is high and its resistance to intergranular corrosion and chloride stress corrosion is obviously improved. Dual phase stainless steel has excellent corrosion resistance and is also a nickel saving stainless steel.

The matrix is austenite or martensite structure, and the common grade of precipitated hardened stainless steel is 04Cr13Ni8Mo2Al, etc. Stainless steel that can be hardened by precipitation hardening (also known as age hardening) treatment.

High strength, but poor plasticity and weldability. Martensitic stainless steel commonly used brands are 1Cr13, 3Cr13, etc., because of the higher carbon content, it has higher strength, hardness and wear resistance, but the corrosion resistance is slightly worse, for higher mechanical properties, corrosion resistance requirements of some parts, such as spring, steam turbine blades, hydraulic valve, etc. This type of steel is used after quenching and tempering. Annealing is required after forging and stamping.

Stainless steel plate and strip for pressure equipment

Special stainless steel for pressure vessels, its classification and code, size, shape and allowable deviation, technical requirements, test methods, inspection rules, packaging, marking and product quality certificate have clear requirements. Common brand number 06Cr19Ni10, 022Cr17Ni12Mo2 number code: S30408, S31603 and so on. Mainly used in food machinery, pharmaceutical machinery and other sanitary equipment.

Main characteristics of stainless steel

weldability

Stainless steel sculpture

Product use of different welding performance requirements are also different. A kind of tableware generally does not require welding performance, even including some pot enterprises. But the vast majority of products need good welding performance of raw materials, such as second class tableware, thermos cup, steel pipe, water heater, water dispenser and so on.

Corrosion resistance

The vast majority of stainless steel products for corrosion resistant performance is good, like a, 2 kinds of tableware, kitchen utensils and appliances, water heaters, water dispensers, etc., some foreign businessmen on corrosion resistance of products also do experiment: in NACL aqueous solution heated to boiling, after a period of time out solution, wash and drying, weight loss, to determine the degree of corrosion (note: When polishing the product, due to the content of Fe in emery cloth or sandpaper, it will lead to rust spots on the surface of the test.

Polishing performance

In today's society, stainless steel products are generally polished in the production of this process, only a few products such as water heater, water dispenser tank do not need polishing. Therefore, the polishing performance of raw materials is very good. The main factors affecting the polishing performance are as follows:

① Surface defects of raw materials. Such as scratches, pitting, pickling and so on.

② Raw material problems. The hardness is too low, it is not easy to shine when polishing (BQ is not good), and the hardness is too low, the surface is easy to appear orange peel phenomenon when deep stretching, thus affecting the BQ. The BQ with high hardness is relatively good.

③ For deeply stretched products, small black spots and RIDGING will appear on the surface of the area with great deformation, which will affect the BQ property.

Heat resistant performance

Heat resistance refers to the high temperature stainless steel can still maintain its excellent physical and mechanical properties.

Influence of carbon: Carbon is an element that strongly forms and stabilizes austenite and enlarges austenite zone in austenitic stainless steel. The ability of carbon to form austenite is about 30 times that of nickel. Carbon is an interstitial element, and the strength of austenitic stainless steel can be significantly improved by solution strengthening. Carbon can also improve the stress and corrosion resistance of austenitic stainless steel in high concentration chloride, such as 42%MgCl2 boiling solution.

But, in the austenitic stainless steel, carbon is often seen as the harmful elements, this is mainly due to the corrosion of stainless steel used in some conditions, such as welding or heating by 450 ~ 850 ℃), carbon steel with chromium in forming high chromium Cr23C6 type carbon compounds which can lead to local chromium depletion, make steel corrosion resistance especially resistant to intergranular corrosion performance degradation. So. Since the 60 s of the development of new cr-ni austenitic stainless steel is mostly carbon content less than 0.03% or 0.02% of the ultra-low carbon type, you can know as the carbon content is reduced, the steel intergranular corrosion sensitivity is reduced, when carbon content less than 0.02% is one of the most obvious effect, some experiments also pointed out that the carbon will also increase the chromium austenitic stainless steel corrosion tendency. Due to the harmful effect of carbon, not only in the process of austenitic stainless steel smelting should be controlled as low as possible carbon content, but also in the subsequent hot, cold processing and heat treatment process to prevent stainless steel surface carburization, to avoid chromium carbide precipitation.

When the number of chromium atoms in the steel is not less than 12.5%, the electrode potential of the steel can be changed from negative to positive. Prevent electrochemical corrosion.

China's stainless steel seamless pipe export keep in a good situation unchanged

China's exports continued to beat expectations in August. Indirect export of stainless steel seamless pipe is still strong. Looking into the trend of steel export (including indirect export, the same below), there are two main factors that will become export support in the future.

First, the depreciation of the RMB exchange rate against the US dollar has improved the export competitiveness of Chinese stainless steel and steel consuming products, including stainless steel coils, stainless steel sheet plates, stainless steel pipes, stainless steel bars. The monetary policies of China and the United States have been at odds this year. While the US Federal Reserve aggressively raised interest rates, China's monetary policy was dominated by China, which implemented relatively loose monetary policy and lowered the reserve requirement ratio and interest rate for many times, resulting in the Sino-US currency spread and the depreciation pressure of RMB against the US dollar. The offshore renminbi fell below the "7" level against the dollar on September 15 and recently fell below the "7.2" level for the first time since February 2008.

Looking forward to the future monetary policy trend of China and the United States, the market generally believes that the Federal Reserve will continue to aggressively raise interest rates due to the serious inflation situation, and the market even once rumored to raise interest rates by 100 basis points. Analysts say that the rate hikes by central banks in the U.S. and Europe could raise the global benchmark interest rate to nearly 4 percent, an increase of more than two percentage points from 2021. The World Bank reckons it may need to raise rates by as much as two percentage points if inflation is to be effectively tamed. In contrast, China's monetary policy is looser and financial institutions are likely to implement new interest rate and reserve requirement ratio cuts. As a result, there may be a new moderate depreciation of the renminbi against the dollar. The depreciation of RMB against US dollar, other conditions unchanged, has improved the export competitiveness of China's stainless steel seamless pipe and steel consuming products.

Second, the tight energy supply and sharp price rise in Europe and other countries will impact their steel production, providing China's stainless steel seamless pipe and steel consumption products demand space. For some time, because of the geopolitical influence, such as the war between Russia and Ukraine, some countries in Europe and Asia have been tight on energy supplies, and their prices have skyrocketed. For example, the price of electricity in France is five times that of last year, and the price of natural gas is 10 times that of last year. Similar situations exist in Germany, Japan and South Korea. The situation is expected to get worse as winter begins. If Russia completely "runs out of gas" to the EU, the production of high-energy-consuming metals and steel-consuming products in the region will suffer a great impact, or the price will be raised due to the cost pressure, which will also increase the demand space for Chinese steel and steel-consuming products. Analysts say that the energy crisis in Europe is turning into an industrial crisis and a crisis in steel production. According to the Confederation of German Industry, Germany's extra energy costs this year amount to more than 10 billion euros, equivalent to a quarter of the average annual sales of the German steel industry. The president of the Confederation of German Industry said that this would cause a major impact on the competitiveness of German steel products, which would be squeezed out by imports. Some companies are already suspending production, waiting for energy prices to fall.

Supported by the above two factors, it is expected that China's stainless steel seamless pipe export year-on-year good situation unchanged. The annual stainless steel seamless pipe direct export to the possibility of increasing, stainless steel seamless pipe indirect export will remain strong.

This article will give you a comprehensive understanding of stainless steel 201 J series

What's the difference among 201 J series stainless steel products? Let me introduce for you:

201 J1 stainless steel: carbon content of 201 J1 stainless steel sheet coils is slightly higher than 201 J4 stainless steel and its copper content is lower than 201 J4 stainless steel. Because of lower processing performance than J4 stainless steel material, 201 J1 stainless steel is suitable for ordinary shallow drawing, deep drawing products large Angle type, such as decorative plate, bathroom products, sink, product pipe, etc.

201 J2, J5 stainless steel: their simple processing in decorative pipe is good, because the hardness of 201 J2 stainless steel and 201 J5 stainless steel is high (when processing temperature is above 96°), which become more beautiful after polishing, but when used in square pipe or in the bend (when processing temperature is 90°),  201 J2 stainless steel pipes and 201 J5 stainless steel sheet coils are easy to burst. In terms of the plate, because of the high hardness, the 201 J2 stainless steel and 201 J5 stainless steel plate surface are more beautiful, and surface treatment such as scrub, polishing, plating color are acceptable. But the biggest problem is bending, bending makes 201 J2 stainless steel sheets and 201 J5 stainless steel plates easy to fracture, planing groove easy to burst, so the ductility is not good.

201 J3 stainless steel: high carbon, low chromium and low copper content. Because of its high carbon content and less copper content, the material is slightly hard, so it does not adapt to the strength of slightly larger bending. Compared with 201 stainless steel J1 material, ductility is not so good, and it is easier to rust than 201 stainless steel J1 material in the same environment.

But in the field of stainless steel narrow strip coils, the emergence of 201 stainless steel J3 material is developed in order to deal with the corrosion resistance requirements of stainless steel pipe factory manufacturers when deformation requirements are not particularly of high demand. Because of its ability to reduce the cost of raw materials, it has been sought after by tube manufacturers in the narrow band strip coil field. 201 J3 stainless steel material can also be easily processed into decorative plate.

201 J4 stainless steel: 201 J4 stainless steel material belongs to high class of 201 stainless steel J series, suitable for deep drawing products of small angle type and deep stretching and salt spray test requirements, such as stainless steel sink, kitchenware, bathroom products, kettle, thermos cup, door hinge, cooker, etc.

201 stainless steel coil Comparison among 201J series Chemical composition (%)

C：Ni：Cr：Mn:Cu:Si:P:S:N:Mo:

J1 stainless steel coil 0.0104 1.210 13.920 10.070 0.810 0.410 0.036 0.003

J2 stainless steel coil 0.1280 1.370 13.290 9.570 0.330 0.490 0.045 0.001 0.155

J3 stainless steel coil 0.1270 1.300 14.500 9.050 0.590 0.410 0.039 0.002 0.177 0.002

J4 stainless steel coil 0.0600 1.270 14.860 9.330 1.570 0.390 0.036 0.002

J5 stainless steel coil 0.1350 1.451 13.269 10.727 0.070 0.584 0.043 0.002 0.149 0.032

From the above figure, we can see that the nickel and chromium compositions of 201 J series stainless steel products are not particularly different, or the law of increasing or decreasing. But in terms of carbon content and copper content, difference is the most obvious.

Copper content: J4 > J1 > J3 > J2 > J5;

The copper content of J4 stainless steel  is in the range of 1-1.5%;

The copper content of J1 stainless steel  is within 0.8-1%;

The copper content of J3 stainless steel  is in the range of 0.4-0.8%;

The copper content of J2/J5 stainless steel  is in the range of 0-0.4.

Copper content determines two factors of the product: rust resistance and product toughness.  The higher the copper content is, the stronger the rust resistance is and the stronger the toughness, the product is more suitable for deep processing, stretching and other process ways. The price of the product is proportional to the amount of copper in the product. The higher the amount of copper is, the more expensive the price is. Stainless steel pipe with high copper content is more suitable for making stainless steel products of different shapes.

Carbon content: J5 > J2 > J3 > J1 > J4;

The higher the carbon content is, the harder the stainless steel product is, of course, also brittle, easy to crack when bending, so the same high carbon content of stainless steel pipe will be easier to rust than the low carbon content of stainless steel pipe.

Hardness arrangement: J5, J2 > J3 > J1 > J4.

J series stainless steel roducts price comparison from high to low: J4 > J1 > J3 > J2, J5.
