Stainless Steel 409 sheet is ferritic stainless steel constructed with 11% chromium. Its composition also contains iron, sulfur, carbon and manganese, making it highly corrosion-resistant and heat-resistant. This makes it ideal for applications in tough environments, such as automotive exhaust systems and other industrial uses where exposure to high temperatures cannot be avoided.
Stainless steel 409 sheet is an extremely versatile metal. It has excellent corrosion resistance, high-temperature strength, formability, and weldability. It is a low-cost stainless steel with good impact toughness. It is often used in automotive exhaust systems and industrial applications such as heat exchangers, boilers, and pressure vessels. It also has superior mechanical properties compared to other grades of stainless steel, like 304 or 316, which makes it highly sought after for many applications.
