Prehardened Hot Rolled Alloy Steel Flat Bar of 1.2311 P20 PDS-3 3Cr2Mo

 

Grade:1.2311 /P20/3Cr2Mo
Standard:AISI, ASTM, BS, DIN, GB, JIS


1.2311 P20 3Cr2Mo Steel Plate Material is a versatile, low-alloy tool steel that is characterized by good toughness at moderate strength levels. The special purpose mold steel 1.2311 P20 3Cr2Mo steel plate is commonly used for plastic injection mold cavities and tooling and for die casting dies for zinc. 1.2311 P20 3Cr2Mo mold steel plate material is typically sold in the pre-hardened condition at a hardness of approximately 300 HBW.

1.2311 P20 3Cr2Mo tool steel differs from area to area in the different countries.Europeans generally use the DIN spec-DIN EN ISO 4957 standard materials (1.2311 and 1.2312), while in Japan steel industry standard, PX5 is the new standard P20. And the Americas Countries, Grade steel P20 is the most and wide used steel grade material. In China, 3CrM2Mo is the P20 steel grade equivalent, which is in the standard GB/T 1299 tool steel specification.
AISI P20 tool steels are nitrided or carburized. These P20 mold steel materials steels are capable of being machined into complex and large dies and molds. Material 1.2311 P20 3Cr2Mo steel plate and round bars are mostly used in the carburized condition. The presence of chromium and nickel enhances the toughness and hardness of mold steel 1.2311 P20 3Cr2Mo grade material.

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

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.
