OPEN ARC FLUX CORED WIRES (HARD FACING)

 

OPEN ARC FLUX CORED WIRES (HARD FACING)

We offer Open Arc Flux Cored Wire for build-up and hard facing applications. Excellent build-up alloy on all weldable steels except 14% manganese steel. The weld metal is machinable and number of layers are not restricted. Some typical applications are surfacing in gears, shafts, sprockets, pinion-gear in sugar industry, rails, base layer prior to use of a more abrasive resistant overlay on palm oil expelled screws, winch drum, crawler tractor links, crane wheels, steel shafts, mine car wheels, sheaves, etc.

 

ROYAL - 7060

DESCRIPTION : Royal 7060 hard facing self shielded (open ARC) flux core wire deposits high chromium high carbon weld metal subjected to hard facing of component for extreme abrasion / erosion under moderate / heavy impact load. The weld deposit is nonmachinable and grinding is possible.

APPLICATIONS : Hardfacing excavator parts, bucket, cutting edges grabteeth, crusher jaws & cones, table liner high chrome crusher rolls in cement plants, catalyst pipes and bends heavy load earth moving equipments etc.
