Corrosion behaviors and mechanical properties of Q235
Excluding the areas pierced by the rust, the maximum average thickness loss of the corroded steel pipes roughly equaled 1.612 mm, and the maximum average depth of the rust pit and the maximum rust pit depth (i.e., the absolute depth) were approximately 1595.314 and 3413.692 µm respectively, with a diameter-to-depth ratio of around 3.0.
