What forms of corrosion can occur in <strong>stainless</strong> steels?

General corrosion - Normally, stainless steel does not corrode uniformly as do ordinary carbon and alloy steels. However, with some chemicals, notably acids, the passive layer may be attacked uniformly depending on concentration and temperature and the metal loss is distributed over the entire surface of the steel.sp.info Stainless steel - WikipediaThe minimum 10.5% chromium in stainless steels provides resistance to ~1,300 °F (700 °C), while 26% chromium provides resistance up to ~2,200 °F (1,200 °C).
