    What is 409 Stainless Steel Strip?

    SUS 304 Mirror 8K Stainless Steel Coil (3)

    Alloy 409 is a versatile ferritic stainless steel, stabilized with chromium and titanium, primarily employed in automotive exhaust systems. With a minimum of 11% chromium, it forms a passive surface film essential for stainless steel corrosion resistance. This alloy offers excellent resistance to high-temperature corrosion, combined with moderate strength, good ductility, and cost-effectiveness.

    Alloy 409 surpasses carbon steel in corrosion resistance, making it a preferred choice in mildly aggressive environments where its ability to resist corrosion and oxidation at elevated temperatures provides significant benefits. It finds application where mechanical properties and corrosion resistance are paramount, prioritizing function over appearance.
