● Steel properties:
  HPM38 13 chrome series stainless steel containing molybdenum, after a special solution made ​​of. Therefore the most suitable and high hardness and corrosion-resistant surface of the plastic mold demanding. And it is a very small thermal deformation, it is also suitable for heat treatment and precision. In addition, the erosion of good maintenance is very favorable for mold.
      * Mirror finish is very good
      * Has a better wear resistance than SUS420J2 corrosion, no chrome
      * Delivery of pre-hardened state, it can be used immediately
      * Suitable for precision mold
● Chemical Composition:
              13 Ming-molybdenum stainless steel patent

● Delivery status: Pre-hardened to 29-33HRC
             Quenched hardness after annealing up to 50-55HRC

● Application:
      For corrosion and heat processing of precision plastic mold steel mirror
      * Transparent mold products: lenses, dressing, etc.
      * Flame-retardant resin molds: home appliances, office equipment, communications equipment, spare parts
      * Electroless Products: Food curtains containers, medical equipment

● Heat treatment:
      Quenching 1000-1050 cooled
      Tempering 200-500 cooled
