    It has high hardness and wear resistance after heat treatment, and has the characteristics of strong hardenability and good dimensional stability.

    Thermal processing specifications

    Start temperature 1050°C, end temperature 850°C, furnace cold.

    Soft annealing specifications

    Under protective gas, heat to 800~850°C, cool to 600°C at a cooling rate of 10°C/h, and then air cool.

    The hardness is ≤250HBw.

    Stress Relief

    If you want to eliminate the residual stress generated after rough machining, the mold should be heated to 650°C, kept warm for 2 hours, then cooled to 500°C, and then empty out of the furnace.

    Quenching and tempering specifications

    The first preheating temperature is 550~600°C, and every 25mm is kept for about 30min; the second preheating temperature is 800~850°C, and every 25mm is kept for about 30min; the austenitizing temperature is 975~1040°C, and every 25mm is kept for about 30min.

    30min, oil (40~70°C) or gas cooling, temper immediately after cooling to 50~70mm.

    1) Low-temperature tempering: Tempering temperature 150 ~200℃, every 25mm should be kept for more than about 60mín, empty, hardness ≥61HRC.

    For low-temperature tempering, a lower austenitizing temperature of 975 ~1025°C should be used.

    2) High-temperature tempering: Tempering temperature is 480~540℃, hold for more than 60 minutes every 25mm, air cooling, tempering more than twice, hardness ≥58HRC.

    For high temperature tempering, a higher austenitizing temperature of 1000 ~1040°C should be used.
