PROPRIETARY Uddeholm Vidar Superior 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: 600–900°C (1112–1652°F). Minimum two preheating steps at 600–650°C (1112–1202°F) and 820–850°C (1508–1562°F). When three preheats are used the second is carried out at 820°C (1508°F) and the third at 900°C (1652°F). Austenitizing temperature: 980–1000°C (1796–1832°F). Soaking time: 30–45 minutes.
Quenching media: high speed gas/circulating atmosphere, vacuum (high speed gas with sufficient positive pressure). An interrupted quench at 350–450°C (662–842°F) is recommended where distortion control and quench cracking are a concern, martempering bath (salt or fluidized bed) at 500–550°C (932–1022°F) or 180–220°C (356–428°F), warm oil, approx. 80°C (176°F). 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:
Temper minimum twice with intermediate cooling to room temperature. Holding time at temperature is minimum 2 hours. Tempering in the temperature range 450–550°C (840–1020°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 0.21 mm. Plasma nitriding at 480°C (895°F) for 10 h and depth of 0.10 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 0.13 mm. Nitrocarburizing in salt bath at 580°C (1075°F) for 1 h and depth of 0.07 mm. - Austenitizing temperature 1000°C (1832°F). Holding time 30 minutes.
