SSC Invar 36 was developed for use in applications where dimensional stability is essential. It is a nickel-iron alloy with a very low coefficient of thermal expansion from cryogenic temperatures to 200 deg C (390 deg F). It is utilized in aerospace composite tooling and die applications, as well as laser components, and cryogenic components and piping: liquefied natural gas production, storage, and transportation. This datasheet provides information on composition, physical properties, and tensile properties. It also includes information on corrosion resistance as well as forming. Filing Code: Fe-158.
