SS 347 Seamless Pipe contains columbium (niobium) which stabilizes the material against sensitization. UNS S34700 has strong resistance to intergranular corrosion and oxidation, especially in high temperature environments up to 870°C (1600°F). Alloy 347 Stainless Steel Tubing is ideal for industries such as aerospace, power generation and chemical processing.
