1038 and 1038H are wrought medium-carbon non-alloy steels that are used in the normalized, cold worked, or quenched and tempered condition. 1038 and 1038H may also be flame or induction hardened. These steels are widely used for moderately and highly stressed parts that require higher strength levels than can be achieved by the lower carbon grades, and where the expense of an alloy steel is not justified. 1038 and 1038H are one of the most widely used steels for threaded fasteners. Their popularity stems from their excellent cold-heading properties, low cost and availability. 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, and joining. Filing Code: CS-230. Producer or source: Data Survey.
