cobalt based welding wires (MIG)

Thiscobalt based welding wires (MIG) good corrosion resistance, heat resistance, and wear resistance up to 800 degrees Celsius. Suitable for high-temperature and high-pressure valves, chemical fiber cutting edges, and more. Available in diameters of 0.8mm-1.6mm with a composition of Co-Cr-W surfacing alloy. Supports customization.

ND-112 aws ERcocr-b In the continuous casting of cobalt based welding wires (MIG), carbon and tungsten content is higher, with moderate hardness, abrasion resistance than aws Ercocr-a good, but slightly less toughness. Surfacing layer has a good corrosion resistance, heat and wear resistance, to 800 degrees Celsius temperature can maintain these characteristics. Surfacing layer can be machined.

Uses: For high temperature and high pressure valves, internal combustion engine valves, chemical fiber cutting edge, high-pressure pump shaft sleeve and liner sleeve, wood saw tooth, hot rolling finishing roller pass
