Megafil A 740 M
375-450 HB, hardfacing and rebuilding alloy for wornout wheels, rails, tires, conveyors, crossings, shafts, bufferlayers prior to hardfacing. excelent wear and abrasion resistance against heavy impact and shock, machinable with carbide tools.
375-450 HB, hardfacing and rebuilding alloy for wornout wheels, rails, tires, conveyors, crossings, shafts, bufferlayers prior to hardfacing. excelent wear and abrasion resistance against heavy impact and shock, machinable with carbide tools.
Due to the high resistance to cracking and excelent toughness, all weld metal requires no buffer layer except on materials considered critical. Suited for wear parts subject to heavy impact and shock. The interpass temperature should be maximum 250ºC. The weld metal is machinable with carbide tip tools, hardening is possible. The maximum hardness is dependent on the base metal and is achieved already in the first layer.
Conveyors and transport surfaces, tires, bucket and loader teeth, cruscher jaws, Bufferlayers, crane wheels, axis, gear parts, winches etc.
