202 Stainless Steel Round Bar

How about the 202 Stainless Steel Bar？

202 Stainless Steel Bar is an Austenitic Stainless Steel material that contains high levels of chromium, manganese and nitrogen. Due to its excellent corrosion resistance, high strength and durability, this steel is used in a wide variety of applications. One of the main applications of 202 stainless steel is the manufacture of kitchen utensils, appliances and sinks. It is also used in the construction industry for cladding, roofing and structural components due to its resistance to corrosion and ability to withstand harsh environmental conditions. In addition,202 stainless steel is used in the automotive industry to manufacture exhaust systems, catalytic converters, and other engine components.

Chemical composition of 202 stainless steel

After a long period of exploration and research, successfully developed a variety of manganese instead of nickel type stainless steel,202 stainless steel in which. According to the formula for calculating nickel equivalent, choose Mn, N, Cu as the main element to replace nickel, due to the ability of nitrogen to form and stabilize austenite, and easy to get and cheap, is more good than bad. Manganese formation of austenite ability is weak, but the ability to stabilize austenite is strong, the price is also cheaper, can be used in large quantities. In addition to ensure corrosion resistance,202 stainless steel in the chromium content of 16% to 18%; to ensure mechanical properties and have a single austenitic organization, nickel content in 4% to 6%, manganese content in 7% to 10%. Cu formation of austenite ability is weak, in the stainless steel solid solubility is limited, but sometimes, a small amount of Cu content on the 

steel of certain mechanical properties and corrosion resistance of certain media will have a beneficial effect.

The hot rolled annealed material of 202 stainless steel intergranular corrosion test, its bending results are no cracks. Its overall corrosion: hot rolled annealed material corrosion rate of 250.66g/(m22h); cold rolled annealed material corrosion rate of 184.78g/(m22h). 202 stainless steel corrosion resistance is slightly lower than 304 stainless steel, suitable for non-polluting and lightly polluted atmospheric conditions, clean water conditions, as well as weakly corrosive acids, alkalis, salts and other media.

Advantages of 202 stainless steel

1, from the processing performance,202 stainless steel can be used in almost all product areas, the application range is very wide. Especially suitable for building decoration, kitchen and bathroom equipment and utensils, household appliances, transportation and industrial sector equipment and components.

2, in the weak corrosion conditions,202 stainless steel can completely replace 304 stainless steel.

3, because the chemical composition of 202 stainless steel has low nickel content, so its price is much cheaper than 304 stainless steel, the price advantage is huge.

Recommendations for the use of 202 stainless steel
From the point of view of the performance of 202 stainless steel itself, in addition to strong oxidizing media, strong acids and low temperature conditions, most of the occasions using 304 stainless steel, basically can be replaced by 202 stainless steel, especially for civil occasions, more suitable for the use of 202 stainless steel.

200 series Stainless Steel Material because of the use of manganese, nitrogen instead of nickel, so its raw material costs are substantially reduced. Generally speaking, the raw material price of 202 stainless steel can be cheaper than the raw material price of 304 stainless steel 20% to 25%. So 202 stainless steel and 304 stainless steel compared with the price advantage is obvious, and 202 stainless steel nickel content is relatively low, resist the nickel price of stainless steel price impact ability is stronger, so 202 stainless steel market price is relatively more stable. In addition, because 202 stainless steel room temperature tensile strength and yield strength are higher than 304 stainless steel, so theoretically can also save stainless steel use, reduce the use of stainless steel direct user costs.

Accompanied by the domestic stainless steel production equipment and process technology progress,200 series stainless steel production process has been basically perfect and mature, especially the RKEF mineral furnace smelting nickel pig iron technology is widely used, to a large extent, to promote the development of 200 series stainless steel. However, it should be noted that there are a lot of 200 series stainless steel on the market, which is not conducive to the expansion of the application of 200 series stainless steel, with the continuous improvement of the corresponding national policy, I believe that the advantages of 200 series stainless steel can really play out!
