The invention relates hot work tool steel. The steel comprises the following main components (in wt. %): 

Hot work tool steel

Steel is described having a chemical composition, in weight-%, of 0.3 to 0.5% carbon (C), from traces to a max. of 1.5% silicon (Si), 0.2 to 1.5% manganese (Mn), 0.01 to 0.2% sulfur (S), 1.5 to 4% chromium (Cr), 1.5 to 5% nickel (Ni), 0.5 to 2% molybdenum (Mo), which at least partially may be replaced by twice as much tungsten (W), 0.2 to 1.5% vanadium (V), from traces to a max. of 0.2% rare earth metals, and a balance essentially of only iron, impurities and accessory elements in normal amounts. In addition, a method for manufacturing a blank of the steel and a process for manufacturing a cutting tool body or holder for cutting tools of the steel is described.
