1.2738 Large Cross-Sectional Pre-Hardende Plastic Mold Steel Tool Steel AISI P20
DIN 1.2738 tool steel is one kind of cold work 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.
Guangda 2738 refined mirror finished plastic die steel replace the large-section pre-hardened 1.2738, 718HH, P20 etc . Guangda has acquired advanced technologies to optimize alloy composite and struction to ensure homogeneous hardness ,polishing performance and machinability .
