Stainless Steel 347 Bars and Rods offer exceptional resistance to corrosion, especially in high-temperature environments. They provide excellent oxidation resistance and are highly resistant to intergranular corrosion, making them ideal for industries like aerospace, chemical processing, and power generation.
These bars and rods are perfect for use in high-temperature applications, including heat exchangers, furnace parts, chemical reactors, and equipment in industries such as aerospace, chemical processing, and power generation, where resistance to oxidation and scaling is crucial.
Stainless Steel 347 Bars/Rods find extensive application in industries that demand high-temperature strength and corrosion resistance. They’re perfect for heat exchangers, furnace components, pressure vessels, boiler tubes, and exhaust systems. Thanks to the stabilization with niobium, these bars are especially well-suited for welded structures in chemical, petroleum, and food processing facilities. Additionally, they are utilized in aircraft exhaust manifolds, power generation systems, and refineries. Their blend of durability, weldability, and resistance to intergranular attack guarantees reliable performance in both oxidizing and moderately corrosive environments.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
