409 Stainless Steel Plate

409 Stainless Steel Plate is a titanium-stabilized ferritic stainless steel（UNS S40900, 1.4512）designed for high-temperature oxidation resistance and cost efficiency. With 10.5–11.75% chromium and titanium addition, it offers good corrosion resistance in mild environments and excellent performance at –20°C to 650°C. Widely used in automotive exhaust systems（mufflers, pipes, catalytic converter shells）and construction machinery components. Cost-effective（about 40% cheaper than 304）, easy to weld and form, ideal for mass production. Top demand in Turkey’s automotive aftermarket and Middle East industrial projects. Available in hot rolled and cold rolled, customized sizes supported. Inquire us now
