P-20 Plastic Mold Alloy Steel
P-20 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 P-20 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 P-20 ensures a uniform cross-sectional hardness.
