DIN 1652-3: 1990 / Bright steel made from case hardening steel; technical delivery conditions

Heat Treatments

  • Carburizing at 880 - 980°C. Core-hardening at 880 - 920°C, case hardening at 780 - 820°C, quenching. Tempering at 150 - 200°C.
  • Hot working 1150-850°C; Soft annealing 650-700°C; Carburize 900-950°C; Cooling after case hardening - water or oil Tempering 150-180°C/min
