In this paper, we describe the laser heat-treating experiment results of three kind tool high-speed steel test samples. After laser quenching and tempering of three kinds of annealed tool high speed steel (W18Cr4V, W9Mo3Cr4V1, W6Mo5Cr4V2) test samples, we used microhardness-measure to test the samples and analyzed such problems as the hardness and depth of hardening quenching layer. Furthermore, after laser quenching and tempering of the quenched and three time tempered high speed steel (W18Cr4V) and its hardness analyzing, we got lase quenching's different results of the samples under different initial heat treating.
