Hastelloy C-22HS has, like the other C-type alloys, excellent corrosion resistance, but it also exhibits high strength, nearly double the other alloys in the family. (See updated datasheet Alloy Digest Ni-742, March 2018.) This datasheet provides information on composition, physical properties, elasticity, and tensile properties. It also includes information on corrosion resistance as well as heat treating. Filing Code: Ni-621. Producer or source: Haynes International Inc.
