On the harsh shores of an offshore facility troubled by chloride-induced corrosion, a shift to AL-6XN Round Bars changed the operational landscape completely. Where other alloys corroded, these round bars consistently delivered extended lifespan and reliability, protecting vital pump shafts, heat exchangers, and pressure vessels. Aurico Alloys LLP’s AL-6XN bars are now preferred by procurement heads, engineers, fabricators, and OEMs across the chemical, marine, oil & gas, pharmaceutical, and power industries globally for performance and compliance.

AL-6XN (UNS N08367, ASTM B691) is known as a superior superaustenitic stainless steel, with high molybdenum (6-7%) and nitrogen additions which provide outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking under aggressive chloride environments. Its chemical blend includes 20–22% chromium, 24–26% nickel, making it a favorite for critical applications exposing metals to seawater, sour gas, and highly reactive media.
Aurico Alloys LLP supplies AL-6XN round bars in a wide size range (3mm to 250mm+) with bright, ground, and polished finishes suitable for rapid machining and fabrication. All shipments come with full mill test certificates (MTC), RoHS/REACH compliance, international packing, and batch traceability, ensuring procurement and engineering teams can trust every delivery for critical process plants and heavy equipment maintenance.
This grade also exhibits excellent mechanical strength (minimum yield strength ~360 MPa, tensile strength >760 MPa), along with superb toughness and elongation, suitable for marine, oil & gas, and power generation where temperature cycling and corrosion risks are severe. For hardware stores and OEMs, AL-6XN offers a practical, tested solution for high-performance and long service life.
High-quality AL-6XN Round Bars ready for industrial use.
