WebApr 5, 2024 · Stainless steels are alloys of iron and carbon containing a minimum of about 10.5% chromium. The presence of chromium ensures the formation of a ultra-thin, invisible, protective, self-healing passive film on the steel surface, mainly made up of chromium oxides and hydroxides; Cr2O3 and Cr (OH)3. Webkeep in mind that scale on stainless steel is far more complex than scale formed on plain mild steel. The scale on stainless steel consists of oxides of chromium, nickel and/or other alloying elements—in addition to iron, and the ease by which it can be removed depends on base metal composition and the thermal treatment to which it is exposed ...
