Plastic Mould Steel Sheet and Flat Bar P20 1.2311 PDS-3
Grade: 1.2311 /P20/3Cr2Mo
Standard: AISI, ASTM, BS, DIN, GB, JIS
1. Product Desciption
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

5.Delivery Condition:
1). Hot rolled, black,
2). Hardness:HRC=28--33,
3). Annealed Hardness:HBS<=235.
6. Application
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 is a prehardened 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.
7. Delivery: For abundant stock, 7-15 days.For customized products, 30-50 days
8. Packaging: We provide the package according to the export standard or as customer's requirements
