Tungsten Carbide Hardfacing Electrode that Resists 2-Body Abrasion and Erosion
Ultimium N112 ®
WELDING • Provides superior abrasion and erosion resistance on ALL weldable steels • Achieves full through wear resistance in a single pass • Deposit hardness attained with a high percentage of sintered tungsten carbides
Ultimium N112 is a sintered tungsten carbide electrode that deposits relatively smooth weld beads and is easily handled. This versatile product can be used to hardface all weldable steels and cast irons. Ultimium N112 provides superior abrasion and erosion resistance throughout the weld deposit with a hardness of HRC 65.
Preparation: Clean the weld area and remove scale and oxide. For parts below 40°F or over 1“ thick, preheat to 150°F. Higher carbon steels require higher preheats (300°F - 500°F).
This versatile product can be used to hardface all weldable steels in the flat and horizontal positions.
TYPICAL APPLICATIONS: APPLICATIONS • Fly-ash Conveyors • Fan Blades • Pug Mill Knives • Dry Cement Pumps • Plastic Mixer Paddles • Tool and rotary drill bits • Muller Plows • Ash Plows • Ore Chutes

TECHNICAL DATA: Hardness as-deposited: Carbide Hardness (kg/mm2): Current & Polarity:
HRC 64-66 2000 or RA 89-91 AC or DCEP(+)
Availability and Recommended Amperages Diameters:

Technique: Maintain a medium to short arc. The electrode should be inclined at a 45° angle in the direction of travel. Weld using stringers or weaving. Be advised that weaving more than 2x the electrode diameter is not advised as it may overheat the base metal and degrade weld deposit wear properties. Prior to extinguishing the arc, back whip the craters to reduce crater cracking. Thoroughly remove slag at the weld deposit toes. Wear Patterns: Selecting an optimum wear pattern can reduce overall costs and welding time. A few common patterns include this shown below...

Post-Welding: Slow cool parts in still air. High carbon steels and air hardenable steels should be covered with a heat retardant blanket.
