AISI Type 446 is a high-chromium (nominally 25%), ferritic, heat-resistant alloy with excellent resistance to oxidation and to various forms of hot corrosion. The alloy is used most commonly for service between 1500 and 2200 F (815 and 1200 C), although its elevated-temperature strength is quite low. Among its many applications are combustion chambers, kiln linings, oil-burner components and annealing boxes. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as creep. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, machining, joining, and surface treatment. Filing Code: SS-407.
