UNS N08367 (6Mo) Pipes & Tubes are pipes and tubes made up of very high grades of stainless steel that can be used for challenging applications involving sea water, brine solutions, and chlorine containing chemicals. These alloys have the name of AL-6XN and these alloys contain molybdenum in quantity of 6% to 7% and nitrogen in quantity of 0.18% to 0.25%. Due to this combination, it is very strong against pitting, crevice corrosion, and stress corrosion caused by chlorides. Seamless pipe and tube can be provided in accordance with ASTM B690, welded pipe in accordance with ASTM B675 and B804, and welded tube in accordance with ASTM B676. Amardeep Steel provides UNS N08367 (6Mo) Pipes & Tubes and many other materials.
