AL Tech 416 EZR is one variation of AISI Type 416, the free-machining martensitic stainless steel that has been one of the staples of the automatic machining industry. It offers higher machinability than Type 416 EZ (Alloy Digest SS-665, December 1996), but is not recommended for bright hardening. This datasheet provides information on composition, physical properties, hardness, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-667. Producer or source: AL Tech Specialty Steel Corporation.
