    Description CM45 is a medium carbon steel is used when greater strength and hardness is desired than in the “as rolled” condition. Extreme size accuracy, straightness and concentricity combine to minimize wear in high speed applications. Turned, ground and polished.  Applications Component parts for vechiles, shafts, bushings, crankshafts, connecting rods and parts for the machine building industry and steel for axes, knives, hammers, etc.  Physical properties (avarage values) at ambient temperature Modulus of elasticity [103 x N/mm2]: 190-210  Density [g/cm3]: 7.84 Soft Annealing Heat to 650-700oC, cool slowly. This will produce a maximum Brinell hardness of 207. Hardening Harden from a temperature of 820-850oC, 830-860oC followed by water or oil quenching. Normalizing Normalizing temperature (oC): 840-880oC. Tempering Tempering temperature: 550-680oC. Forging Hot forming temperature: 1100-850oC.  Machinability Machinability is good, rated at 80% that of the AISI 1112 alloy used as a 100% machining rated steel.
