J and L type 201LN is an austenitic chromium-nickel-manganese stainless steel with a lower carbon content and with added nitrogen compared to J and L type 201 (see Alloy Digest SS-768, November 1999). Type 201LN work hardens to high tensile strengths while maintaining good toughness, even to cryogenic temperatures. 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-771. Producer or source: J & L Specialty Steel Inc.
