Heat Treatment & Tempering

General guidelines for forging and heat treatment processes

Forging & Annealing

  • Forging: Heat slowly to 1205°C. Do not forge below 850°C. Cool slowly in ash or sand after forging.
  • Annealing: Heat to 680°C - 700°C, allow to soak thoroughly. Cool very slowly in the furnace.
  • Normalizing: Heat to 870°C - 913°C and cool in still air.

Hardening & Tempering

  • Hardening: Heat uniformly to 845°C - 890°C until heated through. Quench in oil.
  • Tempering: Heat to 205°C - 649°C depending on the required hardness. Cool in still air.
  • Avoid tempering in the range of 250°C - 375°C to prevent temper embrittlement.
