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
