Electrode with Chromium Carbides for Surfacing.
|Weldalloy III with a soft stable arc which is easy|
to strike and restrike. The weld bead is smooth and crack free. The microstructure of the deposit consist of uniformly dispersed chromium carbides in predominantly martensitic matrix.
|Grind the surface to clean and remove damaged or fatigued material. Use short arc and avoid weaving. While surfacing, medium and carbon steels use Weldalloy LH deposits as buffer layer. For cast irons, Use a buffer layer of Weldalloy 521 or Weldalloy LH. Normally, do not use more than two layers without an intermediate buffer. Relief checks may appear but these will not adversely affect abrasion resistance.||Hardness : 58-62 RC (on second Layer)||Application of this alloy are extensive in earth moving equipments, brick and cement industries,coal and ash handling plants, thermal power plants, bucket edges, pads, lips, teeth, conveyor screws, mixing wings, crushing hammers, jaw crushers, oil expeller worms, scraper blades, fan blades, exhaust blades, scraper bars, sand washing installations,|
agricultural machinery are some of the specific applications.
