Grade 446 Astm A240 Stainless Steel Plates Sheet Polished UNS S44600 3mm 4mm 5mm
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.Grade 446 Stainless Steel Sheets Metal UNS S44600 EN 1.4763 Specification and Dimension Ranges
