Open arc flux cored wire for surfacing and buffer layer application on parts, subjected to metal-to-metal wear (adhesion), moderate impact, thermal fatigue and corrosion. Especially designed for buffer layer application, in order to reduce dilution and crack suseptibility of new continue casting rollers, at the top part of the line. Provides smooth and easily machinable surface on stringer weld bead or weaving technique.Typical Applications: Suitable for buffer layer on new continue casting rolls, before hardfacing layers. Also suitable for surfacing of steam turbines, valves and valve seats.
Gas metal arc (MIG/MAG) welding wire especially developed for hardfacing of parts subjected to high metal-to-metal friction, mineral abrasion and moderate impact. Weld metal can retain it's hardness at high temperatures, till 600°C. Weld metal can be grinded and machined by diamond tools. A tough buffer layer with FCW 30 is recommended before hardfacing, if base metal has high carbon and low weldability. Heat treatment after hardfacing will decrease as-welded hardness. Typical Applications: Ceramic tile moulds, mixer blades, crushers, earth moving equipments, hot cut-offs, shear blades, dies for pressure casting, scraper blades, conveyors, rollers.
