201 Stainless Steel is an austenitic chromium-nickel-manganese stainless steel which was developed to conserve nickel. SS 201 is a lower cost alternative to conventional Cr-Ni stainless steels such as 301 and 304.
Stainless steel 201 is essentially nonmagnetic in the annealed condition and becomes magnetic when cold worked. Type 201 can be substituted for Type 301 in many applications.
