Arnco NonMagXT™ hardbanding eliminates wear and abrasion on specialty non-mag drilling tools. NonMagXT™ is an austenitic material that packs hard phased carbides into a ductile matrix, providing excellent wear characteristics that will protect and extend the life of non-magnetic drilling tools. NonMagXT™’s unique alloy composition facilitates distinctively smooth application to stabilizers, non-magnetic drill collars, MWD/LWD drilling tools and other BHA components. Arnco NonMagXT™ can be re-applied over itself for continuous, long-term protection of drilling assets.

NonMagXT™ is a patent-pending iron-based alloy system that features clear advantages over nickel and other iron-based, non-magnetic hardband products. This unique hardbanding alloy meets non-magnetic standards per API Specification 7-1 with a relative magnetic permeability below the maximum of 1.01 per ASTM A342-3.

The welding characteristics of NonMagXT™ produce a smooth, spatter-free weld deposit ready for field use without excessive preparation or cleanup. NonMagXT™ was specifically designed for easy, crack-free application onto stainless steel components using a low maximum pre-heat temperature of 210° F (99° C) in order to protect the integrity of high-value stainless assets.
