SS 409 Stainless Steel Angles Manufacturer
What are SS 409 Stainless Steel Angles?
SS 409 stainless steel angles are ferritic stainless structural sections designed for applications where moderate corrosion resistance, good formability, and heat resistance up to 675°C are required. They contain 11–12% chromium and are primarily used in automotive and industrial sectors for framing, support, and high-temperature exposure. SS 409 offers an economical alternative to austenitic grades for less corrosive environments.
