Mould Steel

MOULD STEELS typically have lower carbon content—0.36 to 0.40% and chromium and nickel are the main alloying elements. These characteristics allow these materials to be polished to an extremely high finish.

These steels are supplied in a variety of pre-hardened conditions. They are primarily used for low temperature diecasting dies and for molds to form plastics.

Characterised by the following properties, among other things:

  • Wear resistance
  • Polishability
  • Machinability
  • Toughness and hardness
  • Thermal conductivity
