UNS No. G10450 is a plain carbon steel containing nominally 0.45% carbon. It may be used in four conditions: hot rolled, normalized, oil quenched and tempered or water quenched and tempered. It is a general-purpose construction and engineering steel and provides medium strength and medium toughness at low cost. It is suitable for flame- or induction-hardened parts. Among its many uses are axles, shafts, bolts, rods, pipe, wire and tools. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness. It also includes information on corrosion resistance as well as forming, heat treating, machining, joining, and surface treatment. Filing Code: CS-115. Producer or source: Carbon steel mills.
