Tube-Alloy AP-O is a self-shielded, flux-cored wire that deposits an austenitic manganese alloy that can be used for the build-up, overlay and joining of manganese, as well as carbon and low alloy steels. It offers excellent crack resistance and good toughness. The Tube-Alloy AP-O offers excellent impact resistance and upon work hardening, has good abrasion resistance. It also offers improved corrosion resistance compared to mild steel and can be used for unlimited layers of build-up. Tube-Alloy AP-O has a steady arc with minimal slag and spatter. It operates well in automatic applications without chipping between passes. Welding is limited to a horizontal shelf technique with this wire. The Tube-Alloy AP-O hard surfacing wire works well for crusher jaws and cones, crusher mantles and cones, dredge cutter heads and teeth, and crusher rolls.
