PROPRIETARY Uddeholm Vanadis 4 Extra SuperClean Trattamento Termico
- Soft annealing: Protect the steel and heat through to 900°C (1650°F). Cool in the furnace at 10°C (20°F) per hour to 750°C (1380°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 500°C (930°F), then freely in air;
Hardening: Pre-heating temperature: First pre-heating at 600 - 650°C (1110 - 1200°F) and second at 850 - 900°C (1560 - 1650°F). Austenitizing temperature: 940 - 1180°C (1725 - 2160°F), normally 1020°C (1870°F). For large sections, i.e. >70 mm use 1060°C (1940°F). For the very best wear resistance use 1100 - 1180°C (2010 - 2160°F). Soaking time: 30 min. for hardening temperatures up to 1100°C (2010°F), 15 min. for temperatures higher than 1100°C (2010°F);
Quenching media:
- Vacuum (high speed gas at sufficient overpressure, minimum 2 bar)
- Martempering bath or fluidized bed at 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;
Tempering: Choose the tempering temperature according to the hardness required. 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.
Nitriding: temperature should not exceed 525°C (980°F).
Sub - zero treatment: immediately after quenching the piece should be sub - zero treated to between - 70 and - 80°C ( -95 and - 110°F), soaking time 3 - 4 h, followed by tempering. The tempering temperature should be lower 25°C (50°F) in order to get the desired hardness when a high temperature temper is performed.
Impact heat treatment: Hardening between 940°C (1725°F) and 1150°C (2100°F). Holding time 30 min up to 1100°C (2010°F), over 1100°C (2010°F) 15 min. Quenching in air. Tempering 2 x 2 h between 525°C (980°F) and 570°C (1060°F).
Heat treatment after EBM processing: Solution annealing 1100°C (2012°F) for 30 minutes. Tempering 540°C (1004°F) 4 times for 1 hour. - Austenitizing temperature 1020°C (1870°F). Holding time 30 minutes.
