201 stainless steel has the characteristics of certain acid resistance, alkali resistance, high density, no bubbles and no pinholes in polishing. Mainly used for decorative pipes, industrial pipes, some shallow-stretched products.201 type steels are lean nickel alloy austenitic stainless steel designed as a cost-effective solution for 301 grades in various applications.201 stainless steel has a smooth surface, high plasticity, toughness and mechanical strength, and is resistant to corrosion by acids, alkaline gases, solutions and other media. It is an alloy steel that does not rust easily, but not absolutely rust-free.
