201 Stainless Steel Bar
Product Description
201 stainless steel is the steel that is resistant to the corrosion of weak media such as atmosphere, steam and water, while acid resistant steel refers to the steel that is resistant to the corrosion of chemical corrosive media such as acid, alkali and salt.

201 stainless steel bar is composed primarily of iron with between 16 and 18% chromium and less than 0.15% carbon. It also contains small amounts of manganese, nickel, silicon, nitrogen, and copper. In addition, it can be hardened by cold working processes but not heat-treated like 304 or 316 grades, since it has higher formability than the 300 series grades. 201 stainless steel bar has high manganese but low nickel content. So its corrosion resistance is not as superior as 300 series. 201 stainless steel bars are widely used as parts in manufacturing kitchenware, outdoor decoration engineering, urban decoration industry and low-grade household products. They are also used in medical instruments and automotive parts that require flexibility while maintaining strength under pressure.
