Lucefin C55, C55E, and C55R are medium-carbon, non-alloy steels that are used in the normalized, cold worked, or quenched and tempered condition. C55E and C55R may also be flame or induction hardened. C55, C55E, and C55R are used for applications where the higher carbon is needed to improve wear characteristics and where strength levels required are higher than those attainable with the lower carbon grades. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on heat treating, machining, and joining. Filing Code: CS-212. Producer or source: Lucefin S.p.A.

1055, C55, C55E, and C55R are wrought medium-carbon non-alloy steels that are used in the normalized, cold worked, quenched and tempered, or austempered condition. 1055, C55E, and C55R 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. They are also used for applications where the higher carbon is needed to improve wear characteristics. 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-219. Producer or source: Data Survey.

Cf 53 is a wrought medium-carbon (carbon = 0.50–0.57%) non-alloy steel that is used in the normalized, cold worked, or quenched and tempered condition. Cf 53 may also be flame or induction hardened. This steel is 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. 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-239. Producer or source: Data Survey.
