Al Tech 416 EZ 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 hardenability than other AL Tech variations, but does not machine as readily as them. 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, and joining. Filing Code: SS-665. Producer or source: AL Tech Specialty Steel Corporation.
