  Applications of 1.2311 steel
  1.2311 Tool steel is a German Die steel, the steel by “super clean” production process, pre hardened, showing the height of micro pure and excellent homogeneous structure, excellent polishing and light etching engraving. After heat treatment, processing and polishing performance is good, can be carried out, and can be processed, suitable for the surface treatment of chrome, material hardness even (to 400mm thick), good toughness, good mechanical processing performance. Gold microstructure is martensite and bainite structure.
   
  Main be applied to in zinc, aluminum, magnesium and its alloy die-casting mold; Hot-pressing mold, all kinds of hot forging die; Metal extrusion die, die set.
   
  Forging of Plastic mold steel Din 1.2311
  Slowly Heat to 930-1050 °C, keep the temperature to heat thoroughly. Start forging. Finished cool slowly.
   
  Annealing of Din 1.2311 tool steel material
  Heat to 775 to 790 °C, soak enough time, ensure heat thoroughly. then cool in the heat treatment furnace.
   
  Quenching of 1.2311 material
  820-840°C, quench in oil.
   
  Tempering of 2311 steel grade material
  Heat uniformly at the tempering temperature for 1.2311 tool steel material. keep enough time, then cool in air
   
  Advice temperature 100 to 600 °C. more 1.2311 tool steel heat treatment data, pls contact your heat treatment supplier.
