DIN1.2311/ AISI P20 Hot Rolled Round Bar (Dia10-350mm) of Plastic
Mold Steel
Widely using range steel quenching and tempering P20 3Cr2Mo 1.2311 is a versatile, low-alloy tool steel that is characterized by good
toughness at moderate strength levels. The special purpose
Prehardening mold steel P20 steel plate is commonly used for
plastic injection mold cavities and tooling and for die casting
dies for zinc. widely using range steel 1.2311 P20 mold steel plate material is typically sold in the pre-hardened
condition at a hardness of approximately 300 HBW. And with good
cutting mechanical property and Corrosion resistance.
