Prehardned (HRC28-32) Hot Rolled Special Tool Steel 1.2311 P20
1. Product Description
1.2311/P20 Mould Steel is a versatile, low-alloy tool steel that is characterized by good toughness at moderate strength levels.
1.2311 Mould steel is commonly used for plastic injection mold cavities and tooling and for die casting dies for zinc.
P20 is typically sold in the pre-hardened condition at hardness of approximately 300 HBW.
Characteristics as following:
1, Good hardenability
2, Good integral machanical performance under high temperature
3, Good heat-resistance and fatigue-resistance
4, Good performance against liquid metal erosion
5, High putity and homogeneous structure of China's biggest ESR production base for its strict requirement in the whole process of exploitation,smelting,vacuum degassing,ESR,forging,annealing,inspection

6.Application
1.2311 P20 3Cr2Mo plastic mould steel is ideally suited for the production of plastic moulds. Typical applications include die holders, zinc die casting dies, backers, bolsters and injection moulds. The versatility of P20 plastic mould steel with its high tensile characteristics enables uses for a variety of other applications such as shafts, rails and wear strips
Good mechanincal property, make surface have equal hardness after deal with it, Nice polishing , for some mini.Roughness on the surface which can be dealed with induration in advance.It can be used directly after the mould machined, deal with surface induration necessity.
1.2311 P20 3Cr2Mo is a pre-hardened high tensile tool steel which offers ready machineability in the hardened and tempered condition, therefore does not always require further heat treatment .This eliminates the risks, cost, and waiting time of heat treatment and avoids the associated possibility of distortion or even cracking.Subsequent 1.2311 component modifications can easily be carried out.
