PROPRIETARY Uddeholm Sleipner 物理性能
PROPRIETARY Uddeholm Sleipner 热处理
- Soft annealing: Protect the steel and heat through to 850°C (1560°F). Then cool in the furnace at 11°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) and held for 2 hours. Cool slowly to 500°C (930°F) then freely in air;
Hardening: Preheating temperature: 600-650°C (1110-1200°F) and 850-900°C (1560-1650°F); Austenitizing temperature: 950-1080°C (1740-1980°F) but usually 1030-1050°C (1890-1920°F). Holding time: 30 minutes. (A holding time of less than recomended time will result in loss of hardness.) Protect the part against decarburization and oxidation during hardening;
Quenching media: Vacuum (high speed gas with sufficient overpressure minimum 2 bar); Martempering bath or fluidized bed at approx. 200–550°C (390-1020°F); Forced air/gas (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 as fast as possible with regards to acceptable distortion. Martempering should be followed by forced air cooling if wall thickness is exceeding 50 mm;
Tempering: Choose the tempering temperature according to the hardness. Temper at least twice with intermediate cooling to room temperature. For highest dimensional stability and ductility, a minimum temperature of 540°C (1000°F) and three tempers is strongly recommended. Tempering at a lower temperature than 540°C (1000°F) may increase the hardness and compressive strength to some extent but also impair cracking resistance and dimensional stability. However, if lowering the tempering temperature, do not temper below 520°C (970°F). When tempering twice the minimum holding time at temperature is 2 hours. When tempering three times the minimum holding time is 1 hour. - Austenitizing temperature 1030°C (1890°F). Holding time 30 min.
