Abstract
Comprehensive studies of five varieties of hot-rolled microalloyed steels with different chemical compositions were conducted. The influence of structural characteristics of steel on its corrosion resistance was assessed. It was shown that the greatest contribution to the increase in corrosion resistance of steel is made by the chromium content; its increase to 0.5–0.6 wt. % raises the corrosion resistance of steel by 2 times. The high density of nanosized interphase precipitates of carbides and carbonitrides of microalloying elements, such as vanadium and niobium, leads to a decrease in corrosion resistance of steel, while the reduction of corrosion resistance of steel because of the presence of non-metallic inclusions of unfavorable composition is significantly lower.
