CarTech 201 Modified is a nitrogen-strengthened, chromium-manganese-nickel, austenitic stainless steel that provides substantially higher yield and tensile strength than CarTech 304, and has general-corrosion resistance between that of CarTech 430 and CarTech 304. Compared with CarTech 201 (UNS S20100), CarTech 201 Modified has a lower nickel content, which results in higher-strength levels after cold working. This datasheet provides information on composition and physical properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-1319. Producer or source: Carpenter Technology Corporation.

ATI 201 HP is a 200-series, Cr-Mn-Ni austenitic stainless steel. It is comparable to the Cr-Ni stainless steel types 301, 304, and 304L in many respects, and can even provide some advantages over the 18-8 grades in certain applications. Because it possess a very desirable combination of economy plus good mechanical properties and corrosion resistance, it has been used in a wide variety of consumer and transportation applications. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, and joining. Filing Code: SS-1332. Producer or source: ATI.

Armco 201 stainless steel is a non-hardenable austenitic chromium-nickel-manganese stainless steel that is capable of easily attaining high tensile strengths while maintaining excellent ductility when moderately or severely cold worked. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness. It also includes information on corrosion resistance as well as forming, heat treating, and joining. Filing Code: SS-809. Producer or source: AK Steel Inc.

J and L type 201 stainless steel is an austenitic alloy with approximately 6.5% manganese. The nickel and chromium contents are lower than typical to allow more work hardening and to obtain high tensile strengths with excellent ductility. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-768. Producer or source: J & L Specialty Steel Inc.

AK Steel Type 201 is a chromium-manganese-nickel austenitic stainless steel that was developed to conserve nickel. Its properties are similar to those of Type 301. It is a lower cost alternative to Type 301 in certain environments. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on high temperature performance and corrosion resistance as well as forming and joining. Filing Code: SS-1313. Producer or source: AK Steel Corporation.

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.

ALLEGHENY LUDLUM TYPE 201 stainless steel is similar to Type 301 in many ways, with applications ranging from structural members to auto wheel covers. The alloy can be substituted for Type 304 in a variety of mild environments. This datasheet provides information on composition, physical properties, hardness, tensile properties, and compressive strength. It also includes information on heat treating. Filing Code: SS-616.
