Stainless Steel 321 and 321H ERW Pipes are alloyed with chromium (17–19%), nickel (9–13%), and titanium to enhance resistance to intergranular corrosion. Grade 321H contains higher carbon, improving creep strength and high-temperature durability. These pipes offer excellent tensile and yield strength, strong oxidation resistance, and stable mechanical performance under thermal stress. The ERW construction ensures uniform weld seams, good pressure-handling capability, and consistent structural integrity. Together, these features make the tubing ideal for continuous high-heat and corrosive operational conditions.
