What Are Stainless Steel 409 Pipes?

Stainless Steel 409 Pipes are ferritic stainless pipes designed for applications where moderate corrosion resistance and high-temperature strength are required. This grade contains approximately 10.5–11.7% chromium, which provides oxidation resistance and protects the surface from environmental corrosion.

The addition of titanium in the alloy helps stabilize the material during welding, preventing carbide precipitation and improving overall structural integrity.

Common international designations for this grade include:
