Stainless Steel

201

Type 201 Stainless Steel is an austenitic chromium-nickel-manganese stainless steel which was developed to conserve nickel. Nickel is replaced by additions of manganese and nitrogen. It is non-hardenable by thermal treatment, but may be cold worked to high tensile strengths. Type 201 is essentially nonmagnetic in the annealed condition and becomes magnetic when cold worked.

Grade 201 stainless steel is used in structural members, different kinds of severely formed parts, and siding and roofing for railway cars and trailers.
