  • characteristic: 
  • 1. After refining furnace and electroslag remelting for H13ESR steel material, then adding special resistant high temperature alloy steel matrix.The impurity S for the steel is less than 0.003%, P is less than 0.015%, technical standards higher than the North American Die Casting Association (NADCA) and the German DIN standard,
  • 2. Resistance to sudden changes of temperature and thermal stress fatigue
  • 3. when it is in the high temperature ,it remains still high strength 
  • 4. tenacityToughness and good ductility
  • 5. Good cutting and polishing performance 
  • 6. Good hardenability 
  • main application: 
  • 1. Aluminum, magnesium, zinc alloy die-casting mold, 5-8 ten thousand times the service life for aluminum alloy mold . more than 200000 times using life for zinc alloy mold , We suggest to use such hot work die steel .Please refer to our comopany guidance for quenching and tempering.
  • 2. aluminum profile extruding die 
  • heat treatment: 
  • quenching:1020-1050℃(Oil cooling or air cooling) 
  • tempering:180-650℃,to avoid the appearance for the tempering fragility
