Abstract
Study of the effect of high temperature at 1000 °C on the corrosion resistance of GX4CrNiMo16-5-1 martensitic, 316L austenitic, and 904L austenitic stainless steels in 2 M H2SO4/3.5% NaCl solution was done through potentiodynamic polarization technique, potentiostatic method, and optical microscopy analysis. Untreated GX4CrNiMo16-5-1 steel displayed the highest corrosion rate of 4.775 mm/year while untreated 904L steel showed the lowest corrosion rate of 1.043 mm/year. Alteration of the microstructural properties of the steels due to high temperature exposure significantly decreased the corrosion rates of the stainless steels to 2.167, 1.396, and 0.519 mm/year. 904L steel exhibited the least significant metastable pitting activity among the untreated steels due to higher resistance to transient pit formation. Heat treated GX4CrNiMo16-5-1 steel lost its ability to passivate after anodic polarization. The heat treated steels were more resistant to pitting corrosion from observation of pitting potential values. The optical image of untreated and heat treated EN-1.4404 and EN-1.4539 steels was generally similar while the images for EN-1.4405 significantly contrast each other.
