  • Forging:Hot forming temperature: 1100-850oC.
  • Soft annealing:Heat to 650-730oC, cool slowly. This will produce a maximum Brinell hardness of 241.
  • Hardening:Harden from a temperature of 880-930oC followed by oil or water (conditional) quenching.
  • Tempering:empering temperature: 670-730oC.

Mill′s test certificate:

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