    Description CF45 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 Used in gears, shafts, axles, bolts, studs, and machine parts. Physical properties (avarage values) at ambient temperature Modulus of elasticity [103 x N/mm2]: 210 Density [g/cm3]: 7.85 Soft Annealing Heat to 650-700oC, cool slowly. This will produce a maximum Brinell hardness of 207. Normalizing Temperature: 840-870oC. Stress Relieving Stress relieving to remove machining stresses should be carried out by heating to 120-200oC, holding for one hour at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment. Hardening Harden from a temperature of 820-850oC followed by oil or water quenching. Hardness after quenching is 55-61 HRC. Tempering Tempering temperature: 550-660oC. Forging Hot forming temperature: 1100-850oC. Machinability No data.
