HAYNES ALLOY No. 150 is a cobalt-base alloy with excellent thermal shock resistance. It has a higher melting point than other cobalt-and nickel-base high-temperature alloys and resists high-temperature corrosion in air and air-sulfur dioxide atmospheres. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as creep. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: Co-84.
