Abstract ATI 409HP (UNS S40900) ferritic stainless steel was introduced by ATI Allegheny Ludlum to provide improved oxidation and corrosion resistance for automotive exhaust systems in comparison to carbon steel. The alloy was designated "MF-1", indicating its end use: automotive mufflers. The good fabricability of this alloy, combined with its basic corrosion resistance and economy have significantly broadened the utility of ATI 409HP stainless steel. ATI 409HP consists of four grades: UNS S40900, S40910, S40920, and S40930. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on high temperature performance and corrosion resistance as well as forming, machining, and joining. Filing Code: SS-1135.

Abstract Outokumpu Moda 439/4510 is a titanium-stabilized 17% chromium ferritic stainless steel that exhibits improved corrosion resistance, formability, and weldability when compared to Outokumpu Moda 430/4016. It is best suited for mildly corrosive environments. Because of its titanium alloying, Outokumpu Moda 439/4510 can be welded in all dimensions without becoming susceptible to intergranular corrosion. It is possible to use Outokumpu Moda 439/4510 at elevated temperatures, for example the cold end of automotive exhaust systems. This datasheet provides information on composition, physical properties, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-1341. Producer or source: Outokumpu Oyj.
