1.2738 / P20+Ni Large High Demand Plasitc Mould Forged Steel Block
1.2738 steel is produced according to the German DIN standard steel
materials, it has the relative superiority in the similar brand of
steel mechanical properties.
It is mainly used for hot mould processing production, the
application of plastic mold is more common among them.
In addition, the special pre-hard processing of the steel makes it
have a good hardness when it leaves the factory, which can reduce
the heat treatment process in the processing and production of
normal mould and improve economic efficiency.
