Principal Design Features

409 is an alloy designed principally for the automotive exhaust industry, although it has been used successfully in other industrial applications. It combines good elevated temperature corrosion resistance with medium strength, good formability and overall cost. In recent years, however, and with the upcoming US government requirement for a 100,00 mile exhaust capability, other alloys have been becoming more prevalent.
