AISI Types 416 and 416Se are free-maching grades of the low-carbon chromium type stainless steel. The former contains sulfur while the latter contains selenium to produce the free-cutting characteristics. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness, creep, and fatigue. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, machining, joining, and surface treatment. Filing Code: SS-162. Producer or source: Stainless steel mills.

CARPENTER PROJECT 70 STAINLESS TYPE 416 is an improved modification of Carpenter Stainless No. 5, the first free-machining stainless steel ever made. This grade has significantly better machinability than the conventional AISI Type 416. Carpenter Project 70 Stainless Type 416 is suited particularly for automatic screw-machine operations where the longer tool life results in more productive machine time. Among its many uses are fittings, gears, shafts and valve stems. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-459. Producer or source: Carpenter.
