Why Stainless Steel Rust / Corrosion? – Part 1 – Pitting Corrosion!
Although stainless steel is much more resistant to corrosion than ordinary carbon or alloy steels, sometime we see rust on Stainless steel. It is ‘stain-less’ not ‘stain impossible’. Sometime we see rust on Stainless steel. It means it can corrode. Why??? It has some common forms of corrosion in Stainless steel: Pitting corrosion: (pitting corrosion of stainless steel in a chloride-containing environment) Pitting corrosion is an electrochemical oxidation-reduction (redox) process, which occurs within localized holes (cells) on the surface of metals coated with a passive film. The passive layer on stainless steel can be attacked by certain chemical species. The chloride ion Cl- is the most … Continue reading Why Stainless Steel Rust / Corrosion? – Part 1 – Pitting Corrosion!
