6 Moly Metal Products

Arc Alloys Limited offers a large variety of products in 6% Moly (6MO) such as tubing, seamless- and welded pipe, butt weld fittings, flanges, pressure fittings and fasteners:

With its high levels of chromium, molybdenum, and nitrogen, 6 Moly alloys have excellent resistance to a wide range of chemicals and are especially suited for high chloride environments such as brackish water, seawater, pulp mill bleach plants and other high chloride process streams. They provide a cost-efficient alternative to nickel-based alloys and titanium.
