The ASME SA312 TP347 Seamless Steel Square Fin Tube is manufactured from austenitic stainless steel containing columbium (niobium) and tantalum, providing enhanced resistance to intergranular corrosion after exposure to temperatures between 800-1500°F (427-816°C). This alloy is renowned for its exceptional high temperature strength and oxidation resistance.
These fin tubes deliver outstanding performance in demanding environments including chemical processing, petrochemical, power generation, aerospace, oil and gas, and food and beverage industries. Their reliability in high-temperature and corrosive applications ensures long-term operational efficiency.
