    What is 409 Stainless Steel Coil?

    SUS 304 Mirror 8K Stainless Steel Coil (3)

    Grade 409 is a titanium-stabilized ferritic stainless steel, primarily recognized for its widespread application in automotive exhaust systems. It is valued for its commendable mechanical properties and resistance to high-temperature corrosion. This grade, enriched with chromium, is also chosen for various applications requiring reliable weldability and effective corrosion protection. While it has a propensity to develop surface rust and is not typically favored for decorative applications, 409 stainless steel excels in environments where it's exposed to gas corrosion, showcasing robust resistance and durability.

    Features of 409 Stainless Steel Coil

    409 stainless steel is notably recognized for its practicality in environments where resistance to exhaust gas and atmospheric corrosion is essential. While it tends to develop surface rust in most atmospheres, this oxidation layer acts as a protective barrier, preventing further material degradation, albeit at the cost of aesthetic appeal.

    This grade maintains its structural integrity in the annealed condition, showing resilience during cold work processes like mild roll forming, pressing, or stretch-bending, without undergoing hardening. Although its welding performance is considered adequate, it's important to recognize that 409 stainless steel might not be suitable for high-impact structures. Heat-affected zones during welding can experience grain growth, potentially altering the steel's mechanical properties and thereby affecting its overall durability in certain applications.
