Alloy Steel 3.5Ni-1.8Cr-0.4Mo-0.1V is highly suitable for massive components, usually more than four inches thick. It has high hardenability which in a water-spray or water-immersion quench contributes to the formation of sizeable amounts of martensite along with some bainite, and possibly a little ferrite. On tempering, the martensite adds to toughness and lowers the temperature of transition from tough to brittle failure. This steel is suitable for intermediate-duty and heavy-duty generator and turbine rotors, large axles and shafts, large gears and ship forgings. This datasheet provides information on composition, physical properties, elasticity, and tensile properties as well as fracture toughness. It also includes information on corrosion resistance as well as forming, heat treating, and machining. Filing Code: SA-404. Producer or source: Alloy steel mills and foundries.
