Mat.No. 1.1223, DIN Cm60, AISI 1060

Designation by Standards

Chemical Composition (in weight %)

Description CM60 is one of the higher carbon content (0.60%) steels. It is more difficult to fabricate than the lower carbon grades. Applications Shafts, bushings, connecting rods, nechanical engineering components, agricultural hand tools, large forgings, springs, cold rolled strips. Physical properties (avarage values) at ambient temperature Modulus of elasticity [10³ x N/mm²]: 210 Density [g/cm³]: 7.85 Soft Annealing Heat to 650-700^oC, cool slowly in furnace. This will produce a maximum Brinell hardness of 241. Normalizing Normalizing temperature: 820-850^oC. Hardening Harden from a temperature of 800-830^oC, 810-840^oC followed by water or oil quenching. Tempering Tempering temperature: 540-680^oC. Forging Hot forming temperature: 1100-850^oC. Machinability Machinability of CM60 and all of the higher carbon steels is relatively poor. CM60 rates at 55 to 60 % that of the AISI 1112 steel which is considered 100% machinable. Corrosion Resistance This steel is not corrosion resistant. it will rust unless protected. Welding CM60 steel is weldable by all of the welding methods. However with its higher carbon content it is important to use both pre-heat at 150 to 260^oC and post-heat at 590 to 650^oC practice per an approved welding procedure. Cold working Cold working is difficult even in the annealed condition although it may be done by conventional methods but requires greater force than the lower carbon steels.
