Stainless Steel 409 Advantage

Why stainless steel 409 is best for the performance exhaust systems?

409 Stainless Steel is a titanium stabilized ferritic material which basically means it is a steel alloy containing chromium. It contains less nickel and more carbon than 304 stainless steel. Ferritic are best suited for high temperature applications that require corrosion resistance and high strength. This steel is more durable, malleable, and long-lasting compared to other types used for exhaust systems. It is ideal for 4WD vehicles, providing a robust product that performs well in Australian conditions. 409 Stainless Steel is particularly effective for high-temperature applications, handling heat cycling from river crossings, beach driving, and varied weather conditions. It also resists vibrations better and is less prone to cracking than other steel types. Although 409 may develop a brown oxide layer over time, this actually enhances its corrosion resistance.
