Mat.No. 1,1193, DIN CF45, AISI 1045

Обозначение по стандартам

Химический состав (в весовых%)

Описание 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. Применение Used in gears, shafts, axles, bolts, studs, and machine parts. Физические свойства (значения) курсы , при температуре окружающей среды Modulus of elasticity [10³ х Н / мм ²]: 210 Density [g/cm³]: 7.85 Мягкий Отжиг Heat to 650-700^O C, cool slowly. This will produce a maximum Brinell hardness of 207. Нормализация Temperature: 840-870^O С.Снятия напряжения Stress relieving to remove machining stresses should be carried out by heating to 120-200^O C, holding for one hour at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment. Закалка Harden from a temperature of 820-850^O C followed by oil or water quenching. Hardness after quenching is 55-61 HRC. Закалка Tempering temperature: 550-660^O С.Ковка Hot forming temperature: 1100-850^O С.Machinability No data.
