PROPRIETARY Uddeholm Vidar 1 物理性能
PROPRIETARY Uddeholm Vidar 1 热处理
- Soft annealing:
Protect the steel and heat through to 850°C (1562°F). Then cool in furnace at 10°C (20°F) per hour to 650°C (1202°F), then freely in air.
Stress relieving:
After rough machining the tool should be heated through to 650°C (1202°F), holding time 2 hours. Cool slowly to 500°C (932°F), then freely in air.
Hardening:
Preheating temperature: 600–850°C (1112–1562°F) (normally two preheating steps). Austenitizing temperature: 990–1010°C (1814–1850°F), normally 990–1000°C (1814–1832°F). Soaking time: 30–45 minutes. Protect the tool against decarburization and oxidation during austenitizing.
Quenching media:
High speed gas/circulating atmosphere, vacuum (high speed gas with sufficient positive pressure), martempering bath (salt or fluidized bed) at 500–550°C (932–1022°F), martempering bath (salt or fluidized bed) at 180–220°C (356–428°F), warm oil. Temper the tool as soon as its temperature reaches 50–70°C (122–158°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:
Temperature should be choosen according to the hardness required. Temper twice with intermediate cooling to room temperature. Lowest tempering temperature 180°C (356°F). Holding time at temperature minimum 2 hours. Tempering in the range of 425–550°C (797–1022°F) for the intended final hardness will result in a lower toughness.
Nitriding and nitrocarburizing:
Before nitriding, the tool should be hardened and tempered at a temperature at least 50°C (120°F) above the nitriding temperature. Gas nitriding at 510°C (950°F) for 10 h and depth of 0.12 mm or 30 h and depth of 0.20 mm. Plasma nitriding at 480°C (895°F) for 10 h and depth of 0.14 mm or 30 h and depth of 0.19 mm. Nitrocarburizing in gas at 580°C (1075°F) for 2.5 h and depth of 0.12 mm or in salth bath at 580°C (1075°F) for 1 h and depth of 0.07 mm.
