Stainless Steel 409 is a ferritic stainless steel alloy containing approximately 10.5% chromium with small amounts of titanium for stabilization. This composition provides good resistance to oxidation, scaling, and thermal fatigue, particularly in exhaust and high-temperature applications. Mechanically, the alloy offers moderate tensile and yield strength, good toughness, and dimensional stability under thermal stress. Its low carbon content minimizes carbide precipitation, enhancing corrosion resistance in welded structures.
