201 stainless steel generally refers to 201 stainless steel and acid resistant steel. 201 stainless steel refers to 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.

321 stainless steel is an austenitic stainless steel that has excellent corrosion resistance at room temperature, aside from high-temperature strength and creep resistance.

Stainless steel plate surface is bright and clean, with high plasticity, toughness and mechanical strength, acid, alkaline gas, solution and other media corrosion.It is an alloy steel that does not rust easily, but is not absolutely rust free.Stainless steel plate refers to the atmosphere, steam and water and other weak medium corrosion of steel plate, and acid steel plate is acid, alkali, salt and other chemical corrosion medium corrosion of steel plate.
Stainless steel pipe are light weight and are widely used in the manufacture of mechanical parts and engineering structures. Mainly used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial pipelines and mechanical structural components
