Product Description

ASTM A681 Forged Rolled Steel Round Bar 1.2311 P20 3Cr2Mo Forged Steel Square Bar / Steel Plate

1.1.2311 P20 steel introduction
1.2311 AISI P20 Steel  Material is a versatile, low-alloy tool steel that is characterized by good toughness at moderate strength levels. The special purpose mold steel P20 steel plate is commonly used for plastic injection mold cavities and tooling and for die casting dies for zinc. P20 mold steel plate material is typically sold in the pre-hardened condition at a hardness of approximately 300 HBW.
