AL Tech 416EZ and 430F are magnetic, free-machining stainless steels specifically designed for use in high-speed, automatic machining operations. These modifications retain, in so far as possible, the good mechanical properties and corrosion resistance of the basic compositions which they represent. Sulfur is added to produce the free-machining characteristics. AL Tech 416EZ is a martensitic stainless steel and 430F is ferritic. Data are typical; do not use for specification or final design. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness and fatigue. It also includes information on high temperature performance as well as forming, heat treating, and machining. Filing Code: SS-359. Producer or source: AL Tech Specialty Steel Corporation.
