How is corrosion severity determined?

Corrosion severity is assessed by evaluating the condition of the metal, which takes into consideration various stages of corrosion progression. This method encompasses a comprehensive analysis of the extent of deterioration, including any pitting, scaling, or loss of material. Establishing stages allows for a more nuanced understanding of the corrosion's impact on the structural integrity and functional capabilities of the metal being inspected.

Determining corrosion severity strictly by visible rusting is limited, as it does not account for hidden damage beneath the rust. Measuring wall thickness provides useful information about material loss but does not convey the overall condition of the metal, including surface damages that might not be evident. Counting visible dents gives little indication of corrosion severity since dents may not relate directly to corrosion processes or their effects on metals. An approach focused on the stages of corrosion provides a comprehensive assessment that guides maintenance and repair decisions effectively.
