UMCo-50 is a cobalt-chromium-iron heat-resistant alloy with good resistance to thermal shock, oxidatoin, and corrosion by hot gases, slags and molten copper. These characteristics make it highly suitable for use in the metallurgical and glass industries. This datasheet provides information on composition, physical properties, hardness, elasticity, 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-41.
