Description :

A highly alloyed low heat super alloy which deposits an extremely chromium carbide rich weld deposit. Can be used where a combination of hardness and toughness is desired on carbon and alloy steels, manganese steels and cast irons. The deposit resists scaling at elevated temperatures. Suitable for applications where abrasion, impact and erosion are to be resisted.

Applications :

  • Conveyor Screws
  • Wear Plates
  • I. D. Fans
  • Scrapers
  • Dozer Blades
  • Sand Pump Casings

Procedure :

Clean metal surface and gouge out the damaged metal. For cast iron and alloy steels slight preheating is recommended. Incline the electrode at 75° angle from horizontal in direction of travel. For heavy build-ups or surfacing manganese steel a buffer layer of GMSA-26 is recommended to avoid crackings.
