NICKEL VAC X-751 is a modification of NICKEL VAC X-750 carrying higher aluminum content (0.90-1.50 vs 0.4-1.0%). This raises the maximum service temperature 100 F(55 C) to 1600 F(871 C). NICKEL VAC X-751 has a simplified and shortened heat treating cycle relative to NICKEL VAC X-750. It is produced by vacuum induction melting followed by vacuum arc or electroslag remelting. This datasheet provides information on composition, physical properties, elasticity, and tensile properties as well as creep. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: Ni-387. Producer or source: Teledyne Allvac.
