Soft annealing:
750 to 800°C for about 2 to 5 hours
slow controlled cooling of 10 to 20°C per hour to about 650°C; further cooling in air, max. 200 HB
Hardening:
1000°C to 1050°C
15 to 30 minutes keeping curing temperature
quenching in oil/compressed gas/hot bath
obtainable hardness: 53 - 56 HRC
Tempering:
slow heating to tempering temperature immediately after hardening;
minimum time in furnace: 2 hours per 20 mm part thickness;
Tempering twice is recommended.
Application:
1. Use for plastic moulds with high wear resistance and corrosion resistance requirements
2. For transparent plastic moulds
3. For PVC molds
Feature:
Martensite stainless steel,with good machinability and excellent corrosion resistance, polishability, high strength and wear resistance after heat treatment
