P20

Prehardened Plastic Mould Steel

Features

P20 is mold quality alloy steel supplied in the prehardened condition. Special melting and refining practices are utilized to produce a uniform product with exceptional cleanliness. These characteristics allow P20 to be polished to an extremely high finish required for plastic molding. The material is tested to rigorous tool steel standards to ensure uniformity of structure and freedom from defects. P-20 is supplied prehardened to 262/321 BHN. The balanced alloy composition of P20 ensures a uniform cross-sectional hardness.
