PROPRIETARY Uddeholm Holdax 热处理
- Soft annealing: Protect the steel and heat through to 720°C (1330°F), holding time 2 hours. Cool in furnace at 28°C (50°F) per hour to 600°C (1110°F), then freely in air;
Stress tempering: After rough machining the tool should be heated through to 550°C (1020°F), holding time 2 hours, then cool freely in air;
Hardening: (The steel should be fully soft annealed before hardening.) Preheating temperature: 500-600°C (930-1110°F). Austenitizing temperature: 850°C (1560°F). The steel should be heated through to the austenitizing temperature and held at temperature for 30 minutes. Protect the tool against decarburization and oxidation during the hardening process;
Quenching media: Forced air/atmosphere (only for small tools), Oil, Martempering bath 450-550°C (840-1020°F) max. 4 minutes, then cool in forced air. In order to obtain the optimum properties, the cooling rate should be as fast as is concomitant with acceptable distortion. Temper the tool as soon as its temperature reaches 50-70°C (120-160°F).
Tempering: Choose the tempering temperature according to the hardness. Temper twice with intermediate cooling to room temperature. Lowest tempering temperature 180°C (360°F). Holding time at temperature minimum 2 hours.
Nitriding and Nitrocarburizing: before Nitriding material should be rough machined, stress tempered at 550°C (1020°F) and fine machined. Gas nitriding: at 510°C (950°F) for 10 h and depth of case 0.20 mm, 30 h and depth of case 0.30 mm, 60 h and depth of case 0.40 mm. Ion nitriding at 480°C (895°F) for 10 h and depth of case 0.20 mm, 30 h and depth of case 0.25 mm, 60 h and depth of case 0.35 mm. Nitrocarburizing and 580°C (1060°F) in gas for 2.5 h and depth of case 0.25 mm or salt bath for 1 h and depth of case 0.15 mm
