ASTM/ASME 347 Stainless Steel Pipes & Tubes are niobium-stabilized austenitic (UNS S34700) products conforming to ASTM A312/A213 standards, featuring niobium addition (10×C min.) for superior intergranular corrosion resistance in sensitization temperature ranges (425-815°C). This stabilized grade maintains the base 304 alloy's composition (17-19% Cr, 9-12% Ni) while offering enhanced high-temperature performance up to 900°C (1650°F), making it particularly suitable for welded pressure vessels, heat exchangers, and furnace components in chemical processing, power generation, and aerospace applications. The niobium stabilization provides exceptional resistance to carbide precipitation during welding or high-temperature service, ensuring maintained corrosion resistance and structural integrity in demanding thermal cycling environments.
