The 16-25-6 alloy developed by the Timken Roller Bearing Company, Steel and Tube Division, is a nonmagnetic, austenitic, corrosion and heat resistant steel having high creep resistance at elevated temperatures and good corrosion and oxidation resistance. It age-hardens at elevated temperatures after solution quenching, and possesses very high mechanical properties. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness, creep, and deformation. It also includes information on high temperature performance as well as forming, heat treating, machining, and joining. Filing Code: SS-12. Producer or source: Timken Roller Bearing Company.
