Forged Steel Block 1.2311 / P20 / 3Cr2Mo Special Tool Steel for Large-sized Mold
Degree of hardness and the metallography structure are even, the cutting value and the polishing performance are outstanding, can be harden by flame, plates hardly chrome and nitriding. This mould steel can apply to general requirements of the size of the plastic mould and can be operated by electric corrosion.
Applications
Used for various lager-sized or medium-size precision plastic mould and alloy parts.
a, Ideally suited for the production of plastic moulds;
b, Die holders, zinc die casting dies, backers, bolsters and injection moulds;
c, Shafts, rails and wear strips;
1, Features
a, Good hardness uniformity and polishing property,good machining properties.
b, Good integral machanical performance under high temperature, Corrosion resistance
c, Good heat-resistance and fatigue-resistance,high mechanical behavior,cutting mechanical property.
d, Pre-hardened to HRC28-32, can be directly used for mould processing, shorten the construction period.
e, 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.
