Seamless N08028 |UNS N08028|1.4563 Pipe
Our N08028 pipes are specifically designed to outperform standard stainless steels in wet-process phosphoric acid and sulfuric acid services. Due to its high Pitting Resistance Equivalent Number (PREN), this alloy offers outstanding protection against chloride-induced stress corrosion cracking (SCC) and pitting in sour gas (H2S) and marine applications. Through advanced cold-drawing and specialized solution annealing, Tengqi ensures every pipe delivers the mechanical strength and structural stability required for critical chemical processing and oil & gas infrastructure.
"Our N08028 pipes are equivalent to Sanicro 28, providing the same high-level corrosion resistance."
SeamlessN08028 Pipe (N08028 / UNS N08028 / W.Nr. 1.4563) is a high-chromium nickel-iron alloy with 3–4% Mo for sulfuric acid and seawater service. Manufactured by Tengqi in Fujian, China, every heat is fully traceable, hydro-tested and available with third-party inspection (SGS / BV / TUV) on request.
