DIN 1.2738 steel is one kind of plastic mold steel, equivalent to AISI P20+Ni tool steel. While Nickel, chromium and molybdenium are the alloying elements for hardness and toughness. 1.2738 tool steel is specially designed for plastic mold industry, especially for big steel mold parts.
DIN 1.2738 tool steel is usually supplied as pre-hardened/quenched and tempered 280 – 320 HB hardness condition
With good machinability, DIN 1.2738 steels is with better polishability compared to 1.2312 (AISI P20+S).
Material 1.2738 can be through nitrogenation and flame hardening treatment in order to increase the hardness and wearability of mould surface.
