• Less stub / electrode loss
• Extended weld life, does not rust
• Good weldor appeal
• Excellent visability of weld formation
• Welds wear-resistant steels without cracking
• Can hardface over deposit
• Reduces base-metal heat buildup
• Can be machined with carbide tooling
• Withstands the most severe impact conditions

APPLICATIONS

Mil-Arc 56 is an excellent joining and buildup alloy for fabricating and maintaining wear-resistant steels in the earth-moving and heavy manufacturing industries. The high alloyed flux permits welding in a flat and horizontal position. The deposit hardness is 12 to 14 RC with 40% elongation and it rapidly work-hardens up to 45 RC. Mil-Arc 56 can weld dissimilar combinations of steels such as AR plate, T-1, and other carbon steels. Mil-Arc 56 can also join stainless, austenitic manganese, and EVERWEAR wear plate to other steels. Other applications include bucket teeth, hammers, grousers, grisly bars, crusher: jaws, cones, and liners; and almost any application that suffers the effects of high impact. Multiple passes of Mil-Arc 56 will buildup fast and the deposits will not wash-down. Mil-Arc 56 is an excellent underlayment prior to hardfacing with Mil-Arc 13. When a continuous wire is needed, use Mil-Mig 516 with Mil-Mig 113.

FOR OPTIMUM PERFORMANCE:

Use Mil-Prep gouging and chamfering electrode to remove fatigued metal. Grind away any carbon deposits. Bevel heavy sections. While using Mil-Arc 56, Maintain a short arc gap and use stringer beads. You should keep amperage as low as possible that will maintain a smooth, consistent arc. When welding on 11%-14% manganese steel, do not exceed 600 F interpass temperature. Pause and quench with water or air until under the interpass temperature.
