Grade 201 stainless steel strip is a lower-cost alternative to the conventional Cr-Ni austenitic stainless steels, such as 304 strips.
About half of the nickel content of 304 is replaced with alloy additions of manganese and nitrogen. This results in a higher strength than 304.
201 stainless steel strip has relatively lower ductility and formability compared to 301 stainless steel strip.
Grade 201 also has good welding characteristics and low temperature properties.
