Product Description
Alloy Mould Steel Special Steel  for Plastic Mould (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, The main performance
It has excellent hardening depth and good machinability,Delivery to pre hardened and tempered condition,sulfur content is higher than 1.2311.Can impose nitriding processing(about 800HV), plating Nickel or chrome.

2, Application
Mainly used for the degree of the family which do not require extreme large plastic moulds,used as a low melting point of die holder, mould base, etc

3, Grade
4, Chemical composition(%)
5, Phase transition temperature

6, The hardness of delivery
Pre-hardened and temperedHB278-325(950-1100N/mm²)

7, Heat treatment
Annealing1)Heated to720-750°C,Two to four hours heat preservation,
2)Furnace cooling
Stress relief1)Heated to560-650°C and then two to four hours heat preservation
2)Furnace cooling or air cooling
Pre hardened1)Preheat to 600-650°C
2)Heated to hardening temperature 840-840°C and heat preservation
3)Oil cooling
Drawing temper1)Immediately after quenching
2)When the 580-650°C,with the 1/inch to heat preservation

8, Process Flow:   EAF→LF→VD→Argon protection pouring→Multiple forging→(Hollow forging)→Normalizing+Dehydrogenation annealing→UT→Pre-hardening(queching+tempering)→ Finished product test

9, Packing:We provide standard export packing or according to customers' request.
