PROPRIETARY Tyrax ESR Heat Treatments


  • The tensile test samples have been hardened at 1050-1080°C (1920-1975°F), gas quenched in a vacuum furnace and tempered twice at 530°C (985°F) for two hours to the given hardness (56 and 58 HRC).

    The compressive strength test samples have been hardened at 1050°C (1920°F), gas quenched in a vacuum furnace and tempered twice at 525°C (980°F) for two hours to the given hardness.

    Soft annealing: Protect the steel and heat through to 860°C (1580°F). Then cool in the furnace at 10°C/h to 650°C (1200°F), then freely in air.
    Stress relieving: After rough machining the tool should be heated through to 650°C (1200°F) and held for 2h. Cool slowly to 500°C (930°F), then freely in air.
    Hardening: Preheating temperature: 600-850°C (1110-1560°F). Austenitizing temperature: 1050-1080°C (1920-1975°F). Holding time: 30 minutes.

    Sub-Zero treatment: Cryo-treatment in liquid nitrogen (-120°C to -196°C (-185°F to -320°F)) may be carried out for tools with high demands on dimensional stability after heat treatment. This treatment should be performed before tempering. Intricate shapes should however be avoided because of the risk of cracking.
