Tool steel
KPMAXKPM30 Steel for plastic molds
The KPM30 is 30 HRC-type general-purpose steel for plastic molds with superior total balances suitable for everything from mold manufacturing to forming.
 
Features of KPM30

1.Superior welding reparability ●Improved welding crack sensitivity in comparison with the P20
2.Machinability capable of improving the tool service life  ●Better machinability than the P20 offers improved tool service life and machining efficiency.
3.Ultimate mirror surface and drawing machinability in the 30 HRC series ●Allows easy machining after repairing welding defects and suppresses unevenness in the mirror surface and drawing machining.
4.Stable and uniform hardness through to the center for safe deep machining  ●Improved hardening performance in comparison with the P20 ensures uniform hardness inside the material.
