“…Among the latter, manganese is a powerful deoxidizer and desulfurizer in steel, improving steel's quench capacity and workability [6]. In contrast, chromium can significantly improve the strength, hardness, oxidation resistance, corrosion resistance, and wear resistance of steel [7]. Rapid identification of steel and precise determination of the minor and trace metal element concentrations in steel are the essential stages in the recycling and reuse of steel waste, in order to conserve steel resources and guarantee product quality.…”

Laser cleaning is a good alternative to ablate and remove contaminants from different samples. To meet the practical demand, we present the elemental analysis of Q235 steel samples, using laser-induced breakdown spectroscopy (LIBS) to enhance the laser cleaning process. Two samples were selected and kept in water and soil for 4 and 7 days, respectively. Half of the samples were then cleaned using the laser cleaning method. The objectives were to promote the application of laser cleaning, generalize the LIBS for the laser cleaning settings, and identify the different sources of contaminations. Numerous elements were determined by analyzing the LIBS spectra, including Fe, Mn, Cu, Si, Ni, Cr, C, S, and P. After 20 excitation cycles, LIBS signals were comparatively stable and could participate in the ensuing classification modeling procedure. The contaminated samples were noticeably stronger overall than the uncontaminated samples, with the higher the concentration of a certain element, the higher the characteristic spectral intensity of LIBS. The typical spectral intensity and concentration of the two samples were found to be in good agreement.
