About AL-6XN

Skid with AL-6XN alloy

The high strength and corrosion resistance of the AL-6XN alloy make it a better choice than the conventional duplex stainless steels and a cost effective alternative to more expensive nickel-based alloys in applications where excellent formability, weldability, strength and corrosion resistance are essential. It is a cost effective alternative to less expensive stainless steels that do not have the strength or corrosion resistance to maximize life cycles.

AL-6XN alloy has exceptional resistance to chloride corrosion, pitting, crevice corrosion, stress corrosion cracking, and excellent general corrosion resistance to various acid, alkalis and salt solutions.

AL-6XN alloy is identified by the Unified Numbering System (UNS) designation of N08367. AL-6XN alloy is an austenitic stainless steel alloy with high nickel, molybdenum, and nitrogen content. AL-6XN alloy has a face-centered cubic crystal structure similar to other austenitic stainless steels. The alloy is non-magnetic and its magnetic permeability remains low even after severe cold forming.
