PROPRIETARY Böhler Uddeholm A2 热处理
- Soft annealing: Protect the steel and heat through to 850°C. Then cool in the furnace at 10°C per hr to 650°C, then freely in air.
Stress relieving: After rough machining the tool should be heated through to 650°C, holding time 2 hr. Cool slowly to 500°C, then freely in air.
Hardening: Preheating temperature: 650-750°C. Austenitizing temperature: 925-970°C, but usually 940-960°C.
Hardness before tempering approx. 63 HRC (at 990°C, soaking time 60 min.);
Hardness before tempering approx. 64 HRC (at 1010°C, soaking time 45 min.);
Hardness before tempering approx. 65 HRC (at 1030°C, soaking time 30 min.)
*Soaking time-time at hardening temperature after the tool is fully heated through. Protect the part against decarburization and oxidation during hardening.
Quenching media: Martempering bath or fluidized bed at 180-220°C or 450-550°C then cool in air; Circulating air or atmosphere; Vacuum furnace with overpressure of gas at cooling; Oil (only for small and uncomplicated tools). Hardness as a function of hardening temperature.
Tempering: Choose the tempering temperature according to the hardness required by reference to the tempering graph. Temper twice with intermediate cooling to room temperature. Lowest recommended tempering temperature 250°C. Holding time at temperature minimum 2 hr. The tempering graphs are valid for small samples. The hardness received is also dependent on the tool size samples.
