It has been established th at the dynamics of change in the corrosion rate of stainless steel AISI 316L is characterized by a tendency to increase the index by ~5 times with an increase in temperature from 450 °C to 650 °C, as well as a decrease in the index value by ~4.5 times at t he melt temperature of 450 °C and ~1.3 times at the melt temperature of 650 °C with an increase in test duration from 240 to 1440 h, respectively, which is explained by the formation of surface protective oxide films and corrosion products blocking the surface. The steel surface morphology of the formed oxide deposits, the structure and elemental composition were studied by X-ray spectral microanalysis (XSMA) with an energy dispersive spectrometer (EDS). The results of optical microscopy and durometric analysis are also presented. © 2024 The Authors. Published by ELSEVIER B.V.
