Webdepends on the formation of a passive surface. Stainless steel is only “stainless” when the surface oxidizes with chromium and other elements to develop a protective film that resists further oxidation. This protected oxide film is considered a passive surface. To passivate stainless steel, a minimum of 10.5-12% chromium is needed. Webstainless steel were also reported to be more susceptible to rupture in hydrogen at room temperature and lower temperatures as compared to the base metal [22], see also …
