Product Description

AWS A5.21 ERCoCr-B stellite 12 cobalt-based surfacing welding wire price for high pressure valvesAWS A5.21 ERCoCr-B stellite 12 cobalt-based surfacing welding wire price for high pressure valves 

ND-112 aws ERcocr-b In the continuous casting of cobalt-based wire, carbon and tungsten content is higher, with moderate hardness, abrasion resistance than awsErcocr-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
