Laser marking is the modern industrial application for non-contact surface modification. An incidence of a laser beam on the marked surface causes material and structural changes, which lead to optical changes of the surface. The processes during the laser-surface interaction can also affect other surface properties, especially corrosion properties in the case of stainless steel. Laser marking of stainless steel using the fibre pulsed laser SPI G3 is described in the contribution. Possibilities and limitations of steel laser marking are discussed. Some of the latest results of the material analysis and corrosion tests of the laser treated material are presented. Examples of laser marking influence on steel surface, structure and corrosion properties are shown.
