UMCo-51 is a cobalt-base alloy having high stress-rupture strength. It is recommended for high temperature applications where the mechanical stresses are high, and where resistance to abrasion, thermal shock and oxidation are required. This datasheet provides information on composition, physical properties, hardness, and tensile properties as well as fracture toughness and creep. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: Co-51.
