Si: ≤0.4
Mn: 0.5 - 0.8
Ni: ≤0.4
P: ≤0.03
S: 0.02 - 0.04
Cr: ≤0.4
Mo: ≤0.1
MECHANICAL PROPERTIES
Young's modulus, MPa: 200000 - 200000
Tensile strength, MPa: 650 - 880
Elongation, %: 8 - 25
Fatigue, MPa: 275 - 275
Yield strength, MPa: 350 - 550
HEAT TREATMENT
Normalizing: 840 – 900°C,Cooling in air
Soft Annealing: 680 – 710°C,Cooling in furnace
Stress relieve: 550-650°C,Cooling in air
Oil Quenching: 840 – 870°C
Water Quenching: 820 – 850°C
Tempering: 540 – 680°C,Cooling in air
Induction or Flame hardening: 870-900°C
FORGING
The forging temperature range for C45R is usually between 900-1100°C. During the forging process, after the material has reached the desired shape, it should be cooled as slowly as possible in still air or sand to reduce thermal stress and deformation.
