Abstract

Based on the on-site corrosion environment of the Luoruo Railway, this paper conducts laboratory tests including electrochemical accelerated corrosion tests, salt spray corrosion tests, and macroscopic corrosion observation. It compares the indoor accelerated corrosion behaviors of 6 types of steels (Q235, Q235NH, Q335, Q335NH, 304, and 316) selected for the actual project. The results show that: the corrosion resistance of the four steels (Q235, Q235NH, Q335, and Q335NH) is not significantly different, and there is no obvious passivation process in the two electrochemical tests. These steels cannot form stable passive films to resist corrosion in corrosive environments, unlike 316 and 304 stainless steels; 316 stainless steel has better self-healing ability in corrosion prevention. Although the corrosion resistance of 304 stainless steel is slightly lower than that of 316 stainless steel, it still exhibits good performance under certain conditions.
