When a leading offshore gas platform faced rapid corrosion and equipment failure in harsh chloride and acidic environments, the breakthrough came from switching to AL-6XN Sheets. This premium nickel alloy sheet effectively resisted the challenging chloride stress corrosion cracking and pitting that plagued conventional stainless steels, extending plant uptime and reducing costly maintenance. Aurico Alloys LLP proudly offers AL-6XN Sheets that meet the demands of chemical, oil & gas, marine, pharmaceutical, and power generation sectors worldwide.

AL-6XN (UNS N08367, ASTM A240) is a high molybdenum, nitrogen-enhanced super-austenitic stainless steel designed to provide excellent resistance to pitting, crevice corrosion, and stress corrosion cracking in chloride-rich and acidic conditions. Its robust composition, with high nickel and chromium contents plus copper and nitrogen stabilization, places it above 316L and 904L in corrosion resistance and mechanical properties.
Aurico Alloys LLP supplies AL-6XN Sheets in hot-rolled, cold-rolled, annealed, and pickled conditions with full ASTM A240, UNS, and ROHS certification, ensuring authenticity and traceability. Customized solutions for thickness, finishes, and sizes are readily available, supporting OEM, fabricators, and industrial supply chains.
Investing in Aurico’s AL-6XN Sheets secures superior corrosion resistance and mechanical strength critical for maintaining performance, safety, and cost-efficiency in the harshest industrial environments.
High-quality AL-6XN Sheets ready for industrial use.
