Annealing Hardness alter annealing: Stress relieving: Hardening: Hardness obtainable: Tempering Nitriding: Preheating before use: |
Temperature:820-840℃ Holding time:4-6h; Slow turance cooling Max.220HB. Temperature: appr.650℃ Holding time: 2-4 h;Slow cooling Temperature: 1010-1020℃ Quenching:air,hot bath at appr.540℃,oil or Poymer(when oilor polymer, interrupt at 230-280℃), or vacuum hardening. appr.54 HRC. Temperature:540-680℃ To increase toughness,temper 3 times. possible.For die casting models we recommend our nitriding programm no.99. This nitriding layer is free b any compound zone and therefore without any negative infiuence on development of heat checks. 150-350℃-depending on application. |
