446 Stainless Steel Bars and rods are frequently utilised in corrosive, high-temperature settings where oxidation resistance and durability are essential. Boiler baffles, radiant tubes, incinerator parts, heat exchangers, and furnace components are examples of common applications. These bars are also utilised in petrochemical, chemical processing, and cement and steel facilities where exposure to high temperatures and reactive gases is common. They are perfect for thermal processing equipment because of their exceptional scaling resistance at temperatures as high as 1100°C. SS 446 also finds use in kiln linings, exhaust systems, and gas burners, ensuring performance in harsh operating conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
