Grade 446 Stainless Steel

446 is a ferritic stainless steel alloy melted as AOD. This alloy is non-hardenable but has excellent corrosion resistance at very higher temperatures and possesses good mechanical properties.  This grade has poor ductility due to the high chromium content (roughly 25wt%).  Because of the excellent oxidation resistance at high temperatures this grade is widely used as furnace parts and boiler baffles.
