317H Stainless Steel Welded Tubes

Our 317H Stainless Steel Welded Tubes are specifically designed to perform in high-temperature and highly corrosive environments. With a higher carbon content compared to 317 and 317L grades, 317H stainless steel delivers improved strength, enhanced creep resistance, and superior stability under extreme thermal conditions.

The welded construction ensures consistent mechanical strength, structural reliability, and dimensional accuracy, while the smooth internal and external surface finish provides excellent resistance to oxidation, scaling, and corrosion. These tubes also offer strong resistance to pitting, crevice corrosion, and stress corrosion cracking, particularly in chloride-rich environments.

Widely used in power plants, heat exchangers, petrochemical processing, refineries, and high-temperature industrial systems, our 317H stainless steel welded tubes deliver long-lasting durability and dependable performance. Available in a wide range of sizes and customizable specifications, they offer a high-performance and cost-effective solution for demanding industrial applications.
