Inconel alloy MA 754 is an oxide-dispersion-strengthened nickel-chromium alloy produced by mechanical alloying. It offers the advantages of a wrought high-temperature material in service environments where only cast alloys could be used in the past. Its strength in conjunction with its high melting point and microstructural stability makes it an attractive alloy for extreme service applications. This datasheet provides information on composition, physical properties, microstructure, elasticity, and tensile properties as well as fracture toughness, creep, and fatigue. It also includes information on high temperature performance and corrosion resistance as well as forming. Filing Code: Ni-244. Producer or source: Inco Alloys International Inc..
