Heat Resisting Ferritic AISI 446 UNS S44600 Stainless Steel Round Bars
Heat Resisting Ferritic AISI 446 UNS S44600 Stainless Steel Round Bars
446 is a ferritic stainless steel alloy, heat resisting grade.
It 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.
