Abstract
1049 and S50C are wrought medium-carbon (carbon = 0.46–0.53%) non-alloy steels that are used in the normalized, cold worked, or quenched and tempered condition. 1049 and S50C 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. Owing to their low hardenability, their use in the quench hardened and tempered condition is not recommended for large sizes, as the improvement in mechanical properties over the normalized condition is insufficient to justify the additional cost of heat treatment. This datasheet provides information on composition, physical properties, hardness, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: CS-237. Producer or source: Data Survey.
