The article analyses the properties of the surface layer of the C45, X5CrNi18-10, 1.7218, 700MC steel elements after laser cutting, focusing on the stereometric and physical properties of the surface layer. The parameters of 2D and 3D surface roughness and microhardness of the surface layer on diagonal sections are analysed and imperfections are determined. Due to the occurrence of zones of different surface roughness on the surface of the cut elements, the roughness parameters Ra, Rpk and Rvk were measured in the “entrance zone” and “exit zone” of the laser beam. In the case of the C45 and X5CrNi18-10 steel samples, a large difference in the surface quality between the zones was found. For the elements made of the C45, 700 MC and 1.7218 steel, imperfections are located at the lower edge. In the case of all the engineering materials, an increase in microhardness was obtained, ranging from 11% to 137%, and the thickness of the heat affected zone ranged from 10 μm to 250 μm.
