We cater to industries that require affordable corrosion resistance, good formability, and excellent weldability. Our precision-engineered Stainless Steel 439 Angles are built to perform reliably in mildly corrosive and high-temperature settings. With a commitment to strict quality standards, advanced manufacturing techniques, and prompt delivery, we support various applications, including automotive, construction, exhaust systems, and heat exchangers. Our Stainless Steel 439 Angles offer customers durable, low-maintenance solutions for structural frameworks and supports, even in challenging service conditions.
Stainless Steel 439 Angles are ferritic stainless steels that contain approximately 17–19% chromium and very low carbon, along with small amounts of titanium to stabilize the structure and prevent intergranular corrosion. This unique composition ensures good resistance to oxidation and corrosion in moderate environments. They boast a tensile strength of around 415–550 MPa and a yield strength close to 275 MPa, along with impressive ductility, weldability, and formability. These characteristics make Stainless Steel 439 Angles a practical choice for structural and fabrication applications that require durability and ease of processing.
