Forging P20/ B30PH (Baosteel) Prehardening Corrosion Resistance Plastic Mold Steel

 

 

Forging  P20 / B30PH (Baosteel) plastic mold steel is a common alloy tool steel which usually supplied in QT condition. It can give an excellent polished finish.It is one of the most widely used for high demand large-sized or medium-sized precision plastic mould and alloy parts. This grade also provides excellent wear resistance.

 

 

Features


a, Good hardness uniformity and polishing property,good machining properties.


b, Good integral machanical performance when under high temperature, high Corrosion resistance


c, Good heat-resistance and fatigue-resistance,very high mechanical behavior,cutting mechanical property.


d, Pre-hardened to HRC28-32, can be directly used on 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.
