The results of studies of the microstructure of corrosion-resistant steel 12Kh18N10Т after laser cutting are presented. Using metallographic analysis, it was shown that in the laser irradiation zone there is an expansion of austenite grain boundaries, which is usually associated with the precipitation of excess phase along the boundaries of austenite grains and a decrease in the corrosion resistance of steel. Recommendations are given on the need to perform plumbing work to remove metal in the laser impact zone.
