Allegheny Ludlum Type 201 stainless steel has many properties similar to Type 301 and provides excellent strength and formability. Together, Type 201 and Type 201L (see Alloy Digest SS-825, July 2001) account for the greatest tonnage of Cr-Ni-Mn 200 series stainless steels. A typical application is washing machine baskets. This datasheet provides information on composition, physical properties, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, and joining. Filing Code: SS-997. Producer or source: Allegheny Ludlum. See also Alloy Digest SS-616, October 1995.
