Solid 600HF welding wire for hardfacing and rebuilding worn out parts. Offers outstanding abrasion resistance. Common applications include welding of alloyed and non alloyed metal mining parts of earth moving equipment.
Features and Applications
High alloy solid wire (copper-coated) for hard-facing, overlay of all C-Mn steels and even suited for the overlay of cast iron (over buffer layer). This alloy deposits a martensitic structured weld-metal with a hardness of about 54-60 HRC (indicative, as hardness is dictated by many factors, including dilution, hardness of base metal, etc.), characterized by excellent abrasion resistance to moderate impact and high toughness
Weld metal has a Cr-Si structure and, if not tempered, it can only be machined by grinding
Its usage allows to extend the operating life of many wearing parts
Mostly used with semiautomatic and automatic procedures. A cushion layer deposited with basic-coated electrode or basic flux cored wire is essential only with hard-to-weld steelsComponents that are subject to high abrasion, like bucket lips, screws, conveyors, drilling tools, shear blades, sand dredgers
Hard-facing wheels, rolling mill rollers tracks, sliding rollers
Hammers of cylindrical crushers and pneumatic hammers
Cold cutting, drilling and forming tools
Shielding gases: MAG; Ar+CO2 mix gases
Typical Base Material Grades
Carbon-Manganese steels, Cast iron, etc.
