Alloy Steel with 1.2311 Distributor Plastic Mold Steel P20 3Cr2Mo Hot Rolled Steel Plate Sheet Pipe Flat Block Round Bar
Ningshing Precision Machinery began in 1992. We devote oneself to providing One-Stop Solutions to our customers on Tool Steel, Die Steel, Alloy Steel, Mold Base, Machining Parts, CNC Machine.
AISI P20 / DIN 1.2311 Plastic Mold Steel is a kind of plastic mold steel widely used in the world, with good comprehensive mechanical properties, good hardenability. It is easy to get the homogeneous hardness throughout the section for big dimension blocks. Good polish ability, good toughness on the surface. Delivered in Pre-hardening condition, used directly for making molds, that can guaranteegood usability and avoid the deformation in heat treatment.
