Project 70 stainless type 303 and Project 7000 stainless type 303 are free-machining stainless steels of the austenitic chromium-nickel type. They offer significantly improved machinability and longer tool life. These steels are suited particularly for automatic bar-machine and Swiss-type machine operations where longer tool life results in more productive machining time. Applications include shafts, valve bodies, valves, valve trim, and fittings. This datasheet provides information on composition, physical properties, hardness, and tensile properties as well as fracture toughness and creep. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-409. Producer or source: Carpenter.
