DYNAVAR is a corrosion resistant, non-magnetic, age-hardening type cobalt-base alloy with good hot and cold working properties. It is characterized principally by its high fatigue resistance, tensile strength, torque values and corrosion resistance. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, joining, and surface treatment. Filing Code: Co-16.
