Armco 434 is a ferritic stainless steel with good corrosion resistance to mildly corrosive environments and the atmosphere. The alloy is oxidation resistant at temperatures up to 871 deg C (1600 deg F) for intermittent service and up to 788-816 deg C (1450-1500 deg F) for continuous service. It is used for automotive trim and other exterior environments. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming and joining. Filing Code: SS-792. Producer or source: Armco Inc.
