Stainless Steel 446

Stainless Steel 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. Because of the excellent oxidation resistance at high temperatures this grade is widely used as furnace parts and boiler baffles

Application Industries

These materials are not a single material but the name for a family of corrosion resistant steels. Like many scientific breakthroughs, the origins of stainless steel lies in a lucky accident. From the smallest part of the zipper to the largest building skyscraper.
Metal fabrication is widely used across various industrial sectors such as mining, construction, manufacturing, shipbuilding, automotive, aerospace, and energy.
