Hardsurfacing for high manganese steel for severe impact.
DESCRIPTION
Low hydrogen 14% Mn hard steel electrode for joining and surfacing. Resistant against extreme impact, pressure and shocks. Cold tough up to 450HB.
Recovery 130%. Also suitable for high carbon steels besides manganese steels. Deposit is austenitic, extremely tough and work hardens rapidly to about 450 HB.
APPLICATIONS
For surfacing of parts subject to high impact like crusher rills and screens, dipper teeth and lips, dredge parts, shovel parts and idler wheels, manganese rail crossings, syratory crusher mantles, coal crushing jaws, hammer, etc.
DIRECTIONS
Use AC or DC+. Clean weld and grind surface to be built up to remove all work hardened areas, cracks or spalled metal and any other foreign materials. Hold a short arc to avoid excessive loss of manganese. When welding on manganese castings, use as low a current as possible to avoid overheating which cause embrittlement of base material. Beads should be placed so that heat is well distributed, hammer bead surface immediately while cooling to components for shrinkage.
