SAE 1044 is a medium-carbon steel suitable for use in the hot-rolled, normalized, oil-quenched-and-tempered, or water-quenched-and-tempered conditions. It provides medium strength and toughness at low cost and is a general-purpose construction and engineering steel. It is frequently used for flame or induction-hardened parts; its relatively low manganese contributes to a soft, ductile core in these parts. 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: CS-59. Producer or source: Carbon steel mills.
