Plastic Tool Steel P20/DIN 1.2311/618/GB 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 Plastic Tool Steel P20/DIN 1.2311/618/GB 3cr2mo component modifications can easily be carried out.
