An electrochemical accelerated corrosion test was conducted on the Q245R steel sample to simulate the actual corrosion conditions of the carbonization kettle. It was found that corrosion not only causes changes in geometric dimensions, but also causes degradation of the material’s mechanical properties. Tensile tests were conducted on Q235R steel materials at different temperatures, corrosion rates, and strain rates (low strain rate of 10−3−1 s−1, medium strain rate of 10−102 s−1, and high strain rate of 103 s−1). A fitting method was carried out based on the modified Johnson-Cook constitutive equation and MATLAB software, which provides the relationship between its characteristic strength, heat treatment temperature and corrosion rate. According to the results, it can be seen that the fitting curve is in good agreement with the experimental curve.
