Rashdan Pipes and Tubes, a reliable manufacturer and supplier based in Amman, Jordan, offers premium Stainless Steel 321 and 321H Welded Tubing engineered for high-temperature and corrosion-prone environments. Known for precision, durability, and customer-focused service, Rashdan manufactures welded tubing that provides excellent thermal stability, oxidation resistance, and consistent dimensional accuracy. Their 321/321H welded tubing is produced using advanced welding methods and top-quality raw materials to ensure strong weld integrity and long-term performance. Widely used in petrochemical plants, power generation, chemical processing, and high-heat applications, Rashdan’s tubing meets strict international standards, making it a dependable choice for demanding industries.
Stainless Steel 321 and 321H Welded Tubing is alloyed with chromium (17–19%), nickel (9–13%), and titanium for stabilization against intergranular corrosion. Grade 321H features a higher carbon content, enhancing creep strength and high-temperature performance. Both grades offer strong tensile and yield properties, good ductility, and reliable resistance to oxidation. The welded construction ensures uniform weld seams, consistent strength, and good pressure-handling capability. These mechanical characteristics make the tubing suitable for continuous exposure to elevated temperatures and thermal cycling.
