The effect of microstructure variation on the corrosion behavior of high-strength low-alloy (HSLA) steel was investigated. The protective property of the corrosion product layer was also explored. Experimental results reveal that the type of microstructure has significant effect on the corrosion resistance of HSLA steel. The measurement results of weight loss, potentiodynamic polarization curves, and electrochemical impedance spectroscopy indicate that the steel with acicular ferrite microstructure exhibits the lowest corrosion rate. Martensite exhibits a reduced corrosion resistance compared with polygonal ferrite. It is found that the surface of the acicular ferrite specimen uniformly covered by corrosion products is seemingly denser and more compact than those of the other two microstructures, and can provide some amount of protection to the steel; thus, the charge transfer resistance and modulus values of the acicular ferrite specimen are the largest. However, corrosion products on martensite and polygonal ferrite are generally loose, porous, and defective, and can provide minor protectiveness; thus, the charge transfer resistance values for polygonal ferrite and martensite are lower.

“…The trend of corrosion rates of carbon steel in distilled water and brine solution with and without biofilm are confirmed by similar trends in the pH values. The final pH decreases in distilled water when the temperature increases; higher temperature promotes the media to ionize more H + that leads to lowering of the solution pH (Zhang et al, 2015).

Failures of underground oil pipes caused by pitting perforation are investigated in this paper. The chemical composition of the failed oil pipe was analyzed by the direct reading spectrometer, which is in accordance with China national standard GB/T699‐1999 for 20 steel. The failed parts were investigated by means of visual observation, optical microscope (OM) and scanning electron microscope (SEM). Energy‐dispersive X‐ray spectroscopy (EDS) of the inner pits were conducted. The results indicate that the pit on the failed oil pipe is composed of three smaller circular pits, on which a fatigue striation‐like pattern suggests a repetitionary pitting corrosion process, while pitting corrosion in the vertical direction is more serious. The failed position was located in the underground ditch where carbon dioxide (CO2) deposited and underwent wetting and drying cycles with an alternative of rainy and sunny days. Combined with the environment of the oil pipe, the simulation experiment, and corresponding mechanism analysis was conducted to evolve the mechanism of pitting corrosion, initiated by the synergistic effect of CO2 and chloride ions (Cl−), and impelled the production of FeCO3 corrosion agents providing an isolated space in a short time, meanwhile chloride ions proceed to propagate continuously into the inner pit, which could explain pitting corrosion is more serious in the vertical direction.
