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