High Quality 
Mature Technical 
Safe and 201 is a kind of stainless steel. 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.This product 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.
