Abstract
Aubert and Duval PER72 (NiCr18Co15TiMoAI alloy) is a precipitation hardening, nickel-base superalloy. The alloy is solid solution strengthened by additions of chromium, cobalt, molybdenum, and tungsten, while additions of titanium and aluminum provide precipitation strengthening. Aubert & Duval PER72 combines high strength with metallurgical stability as demonstrated by excellent impact strength retention after long exposures at elevated temperatures. It also exhibits good oxidation resistance, as well as excellent resistance to sulfide corrosion. This datasheet provides information on composition, physical properties, elasticity, and tensile properties. It also includes information on low temperature performance, high temperature performance, and corrosion resistance as well as forming and heat treating. Filing Code: Ni-787. Producer or source: Aubert & Duval S.A. (a member of the Eramet Group).
