Carpenter Custom Flo 316HQ is modified from the base alloy type 316 stainless steel by the addition of copper and the lowering of carbon content in order to develop an alloy with corrosion resistance and minimum work hardening upon cold work. This datasheet provides information on composition, physical properties, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-944. Producer or source: Carpenter Specialty Alloys.
