The article proposes a method of mathematical modeling of heat transfer during laser processing of the high carbon steel 9HS (equivalent to DIN 150Cr14). The dimensions of the hardening area are calculated with high accuracy by the isotherm of the critical temperature Ac3. The influence of the main technological parameters (radiation power, laser spot diameter, processing speed) on the depth and width of the hardening zone is shown. The paper also presents the use of the build model for the selection of multitrack processing modes to harden high-carbon steel 9HS to the required depth without surface melting.
