Hot Rolled Steel Plate For Making Mould 1.2312, P20+S With Thickness 16-125mm
1.2312 P20+S Plastic Mould Steel For Special Steel
1.2312/P20+S steel is ideally suited for the production of moulds where improved machinability is required. 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 thefamily which do not require extreme large plastic moulds, Used as a low melting point of die holder , mould base, etc.
