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 use in industries that demand resistance to intergranular corrosion and high-temperature strength. Typical applications include exhaust manifolds, chemical processing equipment, heat exchangers, boiler tubes, pressure vessels, and parts for aircraft engines. Their ability to endure repeated heating and cooling cycles makes them ideal for operations in extreme thermal conditions. Moreover, these bars are favored in food processing, refineries, and marine environments, where both mechanical strength and corrosion resistance are essential for long-lasting reliability.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
