Lucefin Group C50, C50E, and C50R are medium-carbon, non-alloy steels that are used in the normalized, cold worked, or quenched and tempered condition. C50E and C50R may also be flame or induction hardened. C50, C50E, and C50R are widely used for moderately stressed parts, where higher strength levels are needed than can be achieved in the lower carbon grades, and where the expense of an alloy steel is not justified. Owing to their low hardenability, their use in the quenched 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 heat treating, machining, and joining. Filing Code: CS-207.
