Conclusions
With heat treatment to a given hardness, high-speed steels manufactured by atomization have higher mechanical properties than standard steel of similar composition due to the homogeneous fine-grained structure and even distribution of finely dispersed carbide phase. These steels should be quenched from temperatures 20–30° lower than for standard steels.
