Pre-hardened plastic mould steels are widely used for manufacturing mould for plastic because of their four main properties and characteristics:Wear ResistanceCorrosion, ResistanceMirror, Finishability,Surface Workability. These steels are quenched and tempered before being manufactured into mould for plastic, therefore the deformation and cracking of mould resulted from heat treatment can be avoided.
