The invention relates tool steel produced by powder metallurgy and hot isostatic pressing resulting in that the steel is isotropic has a non-amorphous microstructure and has a theoretical density (TD) of > 98 %, the steel consists of in weight % (wt.%):
C 0.2 - 1.5
Si 0.1 - 2.5
Mn 0.1 - 2.5
Mo 10-35
B 0.5-3
balance optional elements, iron and impurities. |
