Abstract  

The corrosion behavior of P265GH low alloy steel and Q235 carbon steel under dry/humid/immersion alternative condition with NaCl and NaHSO3 were investigated by SEM, XRD, FTIR and mass loss analysis. The results show that, the relationship of mass loss to test time for the two steels fits to the same dynamics law. The corrosion products contain a large amount of dense α-FeOOH and amorphous δ-FeOOH. The resistance of rust layer make corrosion rate of the two steels decrease. The mass loss of the two steels is almost the same in the beginning stage, the difference of the mass loss become large with test time. The P265GH low alloy steel exhibited lower mass loss, denser rust layer, and better corrosion resistance rather than Q235 carbon steel.
Key words:  steel      atmospheric corrosion      accelerated corrosion test      corrosion product analysis
