General Properties. Alloy 409 is a general purpose, chromium, titanium stabilized, ferritic stainless steel whose primary application is automotive exhaust systems.It contains 11% chromium which is the minimum amount for the formation of the passive surface film which gives stainless steels their corrosion resistance.lthough Alloy 409 is designed principally for the automotive exhaust industry, it has been successfully used in other industrial applications as well.
