Abstract
A tool steel as well as a method for manufacturing a tool steel for cold-work and/or high-speed-work applications, in particular as an intermediate product for manufacturing cold-work and/or high-speed-work tools with a PVD coating, consisting of the following alloying elements: (all amounts expressed in wt %):
- C=0.55 to 0.75Si=0.70 to 1.00Mn=0.20 to 0.50Cr=4.00 to 5.00Mo=1.80 to 3.50V=0.80 to 1.50W=1.80 to 3.00Co=3.00 to 5.00N=0.02 to 0.10and optionally one or more ofNi≤1.5Cu≤1.0Ti≤1.5Nb≤1.5Ta≤1.5Hf≤1.5Zr≤1.5Al≤1.5B≤0.8S≤0.35P≤0.35and residual iron and inevitable smelting-related impurities.
