201 stainless steel coil is composed primarily of iron with around 18% chromium and less than 0.15% carbon. It also includes small amounts of manganese, nickel, silicon, nitrogen, and copper. It has higher formability than the 300 series grades. Moreover, it can be hardened by cold working processes but cannot be heat-treated like 304 or 316 grades. 201 is a high manganese and low nickel stainless steel with low nickel content and 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.

202 stainless steel is an austenitic chromium-nickel-manganese alloy. It has high ductility, good corrosion resistance and excellent toughness in both high and low temperature environments. 202 stainless steel is one of the most widely used 200 series stainless steel. 202 stainless steel, the austenitic structure is stabilized by the addition of nickel and manganese, thereby preventing the formation of harmful phases, such as sigma phase or chromium carbide. The high nickel content also improves the corrosion and oxidation resistance of the steel at high temperatures.

304 stainless steel is a kind of universal stainless steel material, rust resistance than 200 series of stainless steel material is stronger. High temperature resistance is also better, can be as high as 1000-1200 degrees. 304 stainless steel has excellent corrosion resistance and good intergranular corrosion resistance. For oxidizing acids, it is concluded in the experiment that 304 stainless steel has strong corrosion resistance in nitric acid with a concentration of less than or equal to 65% of the boiling temperature. It also has good corrosion resistance to alkali solution and most organic and inorganic acids.

316 stainless steel coil is composed primarily of iron with around 18% chromium and less than 0.15% carbon. It also includes small amounts of manganese, nickel, silicon, nitrogen, and copper. It has higher formability than the 300 series grades. Moreover, it can be hardened by cold working processes but cannot be heat-treated like 304 or 316 grades. 201 is a high manganese and low nickel stainless steel with low nickel content and 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.

430 stainless steel coil is composed primarily of iron with around 18% chromium and less than 0.15% carbon. It also includes small amounts of manganese, nickel, silicon, nitrogen, and copper. It has higher formability than the 300 series grades. Moreover, it can be hardened by cold working processes but cannot be heat-treated like 304 or 316 grades. 201 is a high manganese and low nickel stainless steel with low nickel content and corrosion resistance.
