Lucefin Group C40, C40E, and C40R are medium-carbon, non-alloy steels that are used in the normalized, cold worked, or quenched and tempered condition. C40E and C40R may also be flame or induction hardened. C40, C40E, and C40R 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. This datasheet provides information on composition, physical properties, hardness, and elasticity. It also includes information on forming, machining, and joining. Filing Code: CS-204. Producer or source: Lucefin S.p.A.
