The combined effect of stress and corrosion on mild steel

Abstract

This paper reports confirmation of the effect of different levels of tensile stress caused by quasi-static loading on corrosion growth and the mechanical properties of corroded steel. Plastic stressed, elastic stressed and non-stressed specimens have been immersed into hydrochloride acid with acidity ranging from 0.00001 to 1 Molar. Corrosion behaviours of the test specimens are measured after 7, 14 and 28 days. The mechanical properties of steel are then measured at three grinding thicknesses (0, 0.5 mm, and 1.5 mm) at different stress and corrosion combined environments to determine the effect of stress and corrosion on mechanical properties of steel and the corrosion penetration depth.
