Описание Unalloyed structural carbon steel. Применение Steels for superficial hardening: Piston bolts, chain bolts, gear shafts, gear wheels, worms and camshafts. Физические свойства (значения) курсы , при температуре окружающей среды Modulus of elasticity [10³ х Н / мм ²]: 210 Density [g/cm³]: 7.84 Мягкий Отжиг Heat to 650-700^O C, cool slowly. This will produce a maximum Brinell hardness of 223. Нормализация Temperature: 830-860^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 810-845^O C followed by oil or water quenching. Hardness after quenching is 57-62 HRC. Закалка Tempering temperature: 550-660^O С.Механические свойства закаленного + темперированное Состояние

Ковка Hot forming temperature: 1050-850^O С.Machinability No data.
