Deskripsi Baja Alat P20
P20 die steel is a kind of mold welding material model, the earliest is P20, followed by P20H, P20Ni have come out. P20 steel is suitable for making plastic molds and die casting of low melting point metals. This steel has good machinability and mirror abrasive properties.
Prehardened plastic die steel. Widely used in China, factory hardness HRC30~42, suitable for large and medium-sized precision molds, suitable for long-term production of high quality plastic molds, used for large mold frame. This steel has good machinability and general polishing ability.

Aplikasi
ASTM P20 Tool steel is a American plastic Die steel material, 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, good toughness, good mechanical processing performance.
Gold microstructure is martensite and bainite structure.
Main be applied to in plastic steel mold. like car injection moulding, PVC plastic injection molding.
