Stainless Steel 321 and 321H ERW Pipes Uses

321 and 321H ERW Pipes made of Stainless Steel 321 are used extensively in those applications that call for exposure for long periods at high temperatures and need resistance to scaling and oxidation. Typical applications include aircraft exhaust systems, thermal oxidizers, heat exchangers, furnace parts, expansion joints, and chemical processing equipment. In power plants, refineries, and oil and gas, they are best suited for the transportation of hot gases or fluids. Due to their resistance to intergranular corrosion following welding, they are a choice for high-temperature application where structural integrity and resistance to corrosion are requirements.
