Good Machinability Pre-hardened HRC30-33 Plastic Mould Steel Plate
1.2312 P20+S
1.2312 tool steel is ideally suited for the production of moulds where improved machinability is required. Typical applications include die holders, zinc die casting dies, backers, bolsters and injection moulds. The versatility of this plastic mould tool steel with its high tensile characteristics enables uses for a variety of other applications such as shafts and wear strips.
1, Features:
1, Alloy tool steel which offers good machineability;
2, Excellent polished finish for large section;
3, Supplied in the hardened and tempered condition ready for machining;
4, In this condition it gives excellent wear resistance.
2, Application:
1, Used for plastic mould, good polish with corrosion-resistin
