● Steel properties:
  8407 SUPREME for the hot work tool steel, the following advantages:
      Resistance to thermal shock and thermal stress fatigue
      High-temperature operation of high intensity
      Toughness, good ductility
      Cutting and polishing of fine
      Have a good full sclerosing
      8407 SUPREME through two innovative improvements made ​​from steel-making method:
  Organization subtle treatment
      1, the steel is more subtle organization
      2, better toughness
      3, a higher intensity of heat between
      4, regardless of the thickness of steel, the longitudinal and transverse strength are consistent
  Electroslag re-melting process
      1, steel cleaner, more uniform material
      2, better thermal fatigue resistance
      3, better resistance to cracking
      4, the polishing performance
