ASTM/ASME A4 Stainless Steel Pipes & Tubes are high-performance austenitic (UNS S66286) products conforming to ASTM A213/A312 standards, featuring a nitrogen-strengthened composition (24-27% Cr, 10-12% Ni, 1.9-2.4% Mo, 0.15-0.25% N) for exceptional creep resistance and oxidation stability up to 700°C (1290°F). This advanced alloy delivers superior high-temperature strength and corrosion resistance compared to standard 300-series stainless, making it ideal for superheaters, heat exchangers, and power generation systems operating under extreme thermal and mechanical stress. The nitrogen-enhanced microstructure provides improved resistance to steam oxidation and carburization while maintaining excellent weldability and fabricability for complex high-heat components in petrochemical and thermal processing applications.
