Hobart McKay Tube-Alloy AP-OThe McKay Tube-Alloy AP-O self-shielded flux cored wire works well for build-up and overlay on austenitic manganese steel, but also for welding on carbon and/or low-alloy steel. Ideal for hard-surfacing applications on a wide range of equipment, the product helps parts sustain high levels of impact by hardening rapidly. Hobart says Tube-Alloy AP-O improves corrosion resistance compared to mild steel or conventional manganese steel hard-surfacing welding wires, and is not limited to a maximum number of build-up layers. It can be used for single or multiple passes in the flat and horizontal position, or for welding vertical surfaces using the horizontal shelf technique.
