It belongs to the high-quality medium carbon, Pre-hardness(28~34HRc) plastic mould steel. It needn't further Make heat treatment for make plastic injection moulding. 1.2312 tool steel properties is very similar with ASTM AISI P20S steel. At most work environment,40CrMnMoS8-6/1.2312 steel is equivalent with P20S tool steel. DIN 1.2312 Tool steel is a plastic injection mould steel material, the steel by “super clean” produce process, pre-hardened, showing the height of micro pure and excellent homogeneous structure, excellent polishing and light etching engraving. After heat treatment, processing and polishing performance is very good, can be carried out, and can be processed, suitable for the surface treatment of chrome, material hardness, good toughness, good mechanical processing performance. Gold microstructure is martensite and bainite structure. Main be applied to in plastic steel mold. like car injection moulding, PVC, PP plastic injection molding etc.
