Good Machining Performance Special Tool P20 Steel Round Bar Black Surface


Main introduction:

P20 / 1.2311 / 3Cr2Mo is an internationally widely used plastic mold steel, its good mechanical properties, high hardenability can make Larger cross-section steel to obtain more uniform hardness, and this steel has good polishing performance and high mold surface finish.

When using this steel mold, usually make quenching and tempering treatment first that the hardness is HRC28 ~ 35 (pre-hardened), and then by cold working manufactured molds can be used directly.

In this way, it can guarantee the using performance of the mould, and avoid deformation of the mold causes by heat treatment.
