PLASTIC MOULD STEEL P20

P20 Steel Plate Material is an adaptable, low-composite tool steel that is described by great durability at moderate quality levels. The extraordinary reason mold steel P20 steel plate is usually utilized for plastic infusion mold holes and tooling and die casting dies for zinc.

P20 mold steel plate material is commonly sold in the pre-hardened condition at a hardness of roughly 300 HBW.P20 tool steels are nitrided or carburized.


These P20 mold steel materials steels are fit for being machined into complex and large dies and molds. Material P20 steel plate and round bars are mostly utilized as a part of the carburized condition. The presence of chromium and nickel enhances the toughness and hardness of mold steel P20 grade material.
