HEAT TREATMENT:

  • SOFT ANNEALING: Heat to 720-750oC, cool slowly in furnace. This will produce a maximum Brinell hardness of 230.
  • STRESS RELIEVING:Stress relieving to remove machining stresses should be carried out by heating to approx. 650oC, holding for 1-2 hours at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.
  • HARDENING:Harden from a temperature of 760-820oC, 800-840oC followed by water or oil quenching. Hardness after quenching is 64-66 HRC.
  • TEMPERING: Tempering temperature: 150-250oC. See the data bellow.
Tempering Temperature Hardness(HRC)
100oC 66
200oC 65
300oC 59
400oC 53

Mill′s test certificate:

EN 10204/3.1 with all relevant data reg. chem. composition, mech. properties and results of testing.
