AISI 446 Ferritic Stainless Steel Chemical Composition & Properties, Grade, Chart and Document

AISI 446 is the name of a stainless steel alloy, which is an excellent choice in hot environments where it is expected to dissolve oxides. The chemical structure of these alloys usually contains approximately 23-30% in chromium and a few other elements like manganese, silicon, carbon and sometimes molybdenum. The offered composition possesses outstanding mechanical strength even at high temperatures, enabling its use in various fields, like petrochemical, chemical processing, and furnaces. AISI 446 shows excellent creep strength and sustained resistance against cyclic oxidation; which stands out as a highly desirable material for application in high-temperature settings. The grade chart and documentation included with it reveal detailed specifics on its mechanical, thermal, and corrosion resistance properties that make it invaluable in strong environments.

AISI 446 Ferritic Stainless Steel Chemical Composition And Grade Table

AISI 446 - a ferritic stainless steel of an excellent high-temperature corrosion and oxidation resistance. Its chemical makeup is basically high levels of chromium, with manganese, molybdenum and silicon as additions, and carbon and nitrogen in low quantities. It is special because this feature lets it equaling good performance in hot industrial furnaces and exhaust systems. AISI 446, the ferritic stainless steel grade, belongs to this family. The balance between strength , heat resistance andof corrosion resistance is found in this material and it is suitable for a wide variety of demanding applications.
