ASTM ASME 304N2 Stainless Steel Pipes & Tubes 0Cr18Ni10NbN China Manufacturer

ASTM/ASME 304N2 Stainless Steel Pipes & Tubes are high-nitrogen austenitic (UNS S30452) products manufactured to ASTM A213/A312 standards, featuring elevated nitrogen content (0.15-0.30%) for exceptional strength enhancement while maintaining the corrosion resistance of standard 304 grade (18% Cr, 8% Ni). This nitrogen-strengthened variant delivers approximately 40% higher yield strength than conventional 304, with improved resistance to pitting and stress corrosion cracking. The material is particularly suitable for structural applications in aggressive environments, including chemical processing systems, offshore platforms, and high-pressure piping, where both mechanical robustness and corrosion resistance are critical. Its enhanced properties are achieved without compromising weldability or formability, making 304N2 an optimal choice for demanding industrial applications requiring reduced wall thickness or increased load-bearing capacity.
