PROPRIETARY U S 6 Heat Treatments

  • Annealing at 820 - 840°C for 4 - 6h, slow furnace cooling. Stress relieving at appr. 650°C for 2 - 4h, slow cooling. Hardening at 990 - 1020°C, quenching in air, hot bath at appr. 540°C, oil or polymer (when oil or polymer, interrupt at 250 - 300°C), or vacuum hardening. Tempering at 520 - 700° C, to increase toughness, temper 2 or 3 times. Nitriding possible within limits. Preheating before use 200°C (for hot work only).
