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. Producer or source: Lucefin S.p.A.

SAE 1050 is a water- and oil-hardening grade of carbon steel recommended for applications where a shallow-hardening steel of moderate strength and toughness suffices. It is commonly used for parts where induction hardening is employed and may be used in the austempered condition. 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 heat treating, machining, joining, and surface treatment. Filing Code: CS-110. Producer or source: Carbon steel mills.

1050, 1053, C50, C50E, and C50R are wrought medium-carbon non-alloy steels that are used in the normalized, cold worked, quenched and tempered, or austempered condition. 1050, 1053, C50E, and C50R 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, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: CS-218. Producer or source: Data Survey.

1050, 1053, C50, C50E, and C50R are wrought medium-carbon (carbon = 0.47–0.55%) non-alloy steels that are used in the normalized, cold worked, quenched and tempered, or austempered condition. 1050, 1053, C50E, and C50R may also be flame or induction hardened, nitrided, or nitrocarburized. 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 forming and heat treating. Filing Code: CS-248.
