PROPRIETARY Uddeholm QRO 90 Supreme 热处理
- Soft Annealing
Protect the steel and heat through to 820°C (1500°F). Then cool in the furnace at 10°C (20°F) per hour 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), holding time 2 hours. Cool slowly to 500°C (930°F), then freely in air.
Hardening
Pre-heating temperature: 600 - 850°C (1110 - 1560°F) normally in two pre-heating steps. Austenitizing temperature: 1020 - 1050°C (1870 - 1920°F).
Protect the part against decarburization and oxidation during hardening.
Quenching Media
High speed gas/circulating atmosphere, vacuum (high speed gas with sufficient positive pressure), an interrupted quench is recommended, martempering bath or fluidized bed at 550°C (1020°F), martempering bath or fluidized bed at 180 - 220°C (360 - 430°F), warm oil.
Temper the tool as soon as its temperature reaches 50 - 70°C (120 - 160°F). In order to obtain the optimum properties for the tool, the cooling rate should be fast but not at a level that gives excessive distortion or cracks.
Tempering
Choose the tempering temperature according to the hardness required. Temper minimum twice with intermediate cooling to room temperature. Lowest tempering temperature 600°C (1110°F). Holding time at temperature minimum 2 hours. To avoid “temper brittleness” do not temper in the range 500 - 600°C (930 - 1110°F).
Nitriding: Before nitriding, the tool should be hardened and tempered at a temperature minimum 25 - 50°C (50 - 90°F) above the nitriding temperature. Gas nitriding at 510°C (950°F) for 10 h and depth of 0.16 mm or 30 h and depth of 0.27 mm. Plasma nitriding at 480°C (895°F) for 10 h and depth of 0.18 mm or 30 h and depth of 0.27 mm.
Nitrocarburizing in gas at 580°C (1075°F) for 10 h and depth of 0.18 mm or 30 h and depth of 0.27 mm. In salt bath at 580°C (1075°F) for 1 h and depth of 0.13 mm - Austenitizing temperature 1870°F (1020°C). Holding time 30 minutes.
