Mil-Arc is a chrome and boron carbide hardfacing electrode that is 64 RC as deposited. With the extra alloying ingredients and grain tighteners, Mil-Arc 11 gives you a hard and tough deposit that will withstand an impact. In comparison, it is the hardest commercially made hardfacing electrode other than tungsten carbide for a fraction of the price. Some of the applications include: dredge cutter teeth, tool joints and drill collars, brick dies, chutes, conveyor flights, exhaust fan blades, rock washer paddles, plow shoes, and any other application where severe abrasion is occurring.

Mil-Arc 11 is designed for a two pass maximum build, but it can be inner-alloyed with Mil-Arc 56. You can also use it as a hardfacing cap over Mil-Arc 50 or Mil-Arc 54. Consider Mil-Mig 111 for your continuous wire needs.


Mil-Arc 11 operates best using DCEP, although it runs smoothly on AC and DCEN. Prepare the surface by removing any damaged and fatigued metal. You should keep amperage as low as possible that it will maintain a smooth, consistent arc. Use stringer beads. For high alloys and heavy sections preheat as per base metal recommendations.
