PROPRIETARY Uddeholm Hotvar 热处理
- Unless otherwise is indicated all specimens were hardened at 1050°C (1920°F), quenched in air and tempered 2+2 h at 575°C (1070°F) to a hardness corresponding to 56 HRC. General recommendations: Soft annealing: Protect the steel and heat through to 820°C (1500°F). Then cool in the furnace at 11°C (20°F) per hour to 600°C (1110°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 350°C (660°F), then freely in air; Hardening: Pre-heating temperature: first step at 480-600°C (895-1110°F), second step at 850 (1560°F). Austenitizing temperature: 1050-1070°C (1920-1960°F), normally 1050°C (1920°F) but when maximum hardness is required the normally temperature is 1070°C (1960°F). (At 1050°C (1920°F) - Soaking time: 30 min, Hardness before tempering for d = 25 mm: 61 ± 1 (Oil) and 59 ±1 (Air); At 1070°C (1960°F) - Soaking time: 20 min, Hardness before tempering for d = 25 mm: 62 ± 1 (Oil) and 60 ±1 (Air)); Quenching media: High speed gas/circulating atmosphere, Vacuum (high speed gas with sufficient positive pressure), Martempering bath or fluidized bed at 450-550°C (840-1020°F), Martempering bath or fluidized bed at approx. 180-220°C (360-430°F), Warm oil, approx. 80°C (175°F). (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. Temper minimum twice with intermediate cooling to room temperature. Holding time at temperature minimum 2 h.
