Alloy 740H (see Alloy Digest Ni-613, September 2003) is a precipitation-hardenable Ni-Cr-Co alloy containing molybdenum and niobium. The primary application for the alloy is boiler tubes for advanced ultra-supercritical steam boilers. This data sheet covers a modification of that alloy to correct two problems, i.e., the eta-phase formation with a loss of impact strength between 750–800 deg C (1382–1472 deg F) and to render the alloy more weldable. This datasheet provides information on composition, physical properties, elasticity, and tensile properties. It also includes information on high temperature performance as well as forming, heat treating, machining, and joining. Filing Code: Ni-716. Producer or source: PCC Energy Group.
