PROPRIETARY Böhler-Uddeholm Holder Heat Treatments

It is intended for use in the hardened and tempered condition, i.e., the delivery condition.
Stress Tempering: After rough machining, the tool should be heated through to 900°F, and held for a minimum of 2 hours once the entire tool is soaked through. Cool slowly to room temperature. Stress tempering temperatures in excess of 900°F may result in a permanent loss of strength, hardness, and/or dimensional tolerances.
Flame and induction hardening: Can be flame or induction hardened to a hardness of approx. 50 RC. Cooling in air is preferable. Smaller pieces may however require forced cooling. Hardening should be immediately followed by tempering.
Gasnitriding: Nitriding gives a hard surface which is very resistant to wear and erosion. A nitrided surface also increases the corrosion resistance. The surface hardness after nitriding at a temperature of 525°C in ammonia gas will be approx. 650HV.
