201 Stainless Steel

UNS S20100

The nickel in Type 201 is lower than Type 301 and is replaced with a manganese-nitrogen combination allowing this type to develop high yield and tensile strength in the annealed condition. Although the mechanical and corrosion properties are alike, its general uses do not cover the field of the comparative 300 series. Type 201 is nonmagnetic when annealed yet slightly magnetic when cold-worked. Resistance to abrasion is favorable.

Type 201 is normally limited to nearly flat or shallow drawn products such as automotive trim, builder’s hardware comprised of window and door components, flatware, rapid transit cars and trailers.
