Understanding Corrosion and How to Protect Against It ...

Mar 11, 2002  When iron or steel corrodes, the result is iron oxide, or what we call rust. Steel is mostly composed of iron ore. In its natural state, iron ore looks much like rust: dark red and finely grained, with a tendency to hold moisture. Iron ore is a stable substance until it is converted into iron or steel, naturally weaker elements.
