Abstract :
Present study the effect of H2S concentration and temperature on corrosion behavior was studied for ASTM-A516-Gr70 in sour simulated solution. The dissolved H2S was created by chemical reactions in solution. Na2S•9H2O was chosen as test material to replace H2S because of the toxicity of H2S. The specimens were immersed into synthetic seawater saturated with H2S where corrosion behavior was evaluated by potentiodynamic polarization, weight loss, and scanning electron microscopy (SEM). The result show that the hydrogen induced cracking can take place in H2S containing solution for A516-Gr70 steels.
