Abstract: For an important city northwest of Mexico, Tijuana's metallic industry utilises two types of stainless steel, SS304 and SS316, to manufacture the metallic structures of bridges built to modernise the city. This investigation was made as a comparative analysis of the utilisation of SS304 and SS316 regarding the corrosion resistance and the protection of both types of stainless steel using the Auger electron spectroscopy (AES) technique and the scanning electron microscopy (SEM). The chemical compounds, crystalline structure and the physicochemical properties of each stainless steel were evaluated. This scientific study was made in 2023.

Keywords: industry; SS304; SS316; Auger electron spectroscopy; AES; environmental agents; Mexico.
