摘要
We study the influence of various electrolytes (chloride, sulfate, carbonate, phosphate, and nitrate ions) on the pitting corrosion resistance and corrosion-cracking resistance characteristics of 17G1S pipe steel in an NS-4 neutral model soil medium. The correlation between these characteristics and possible mechanisms of cracking of pipe steel in the investigated media are analyzed.
