Description
Unalloyed structural carbon steel.
Applications
Steels for superficial hardening: Piston bolts, chain bolts, gear shafts, gear wheels, worms and camshafts.
Physical properties (avarage values) at ambient temperature
Modulus of elasticity [103 x N/mm2]: 210
Density [g/cm3]: 7.84
Soft Annealing
Heat to 650-700oC, cool slowly. This will produce a maximum Brinell hardness of 223.
Normalizing
Temperature: 830-860oC.
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 810-845oC followed by oil or water quenching. Hardness after quenching is 57-62 HRC.
Tempering
Tempering temperature: 550-660oC.
