China Stellite12 Cobalt-Based Cast Rod for Surfacing Welding

Product Name:
Stellite 12 cobalt-based cast rod
Model:
AWS A5.21:2001 ERCoCr-B
Description:
Stellite12 continuous casting cast rod has a high content of tungsten, so the
hardness of the matrix is high, and the wear resistance is strong. The surfacing
layer has good corrosion resistance, heat resistance and wear resistance, and
can maintain these characteristics at a high temperature of 800 ºC, and can be machined.
Uses: Used for surfacing welding of high temperature and high pressure valves,
internal combustion engine valves, various blades in the chemical industry, shaft
sleeves of high pressure pumps, wood saw teeth, hot-rolled finishing pass rolls,
screw push rods, etc.
Hardness at room temperature: HRC46-51
Welding method: use oxygen-acetylene carbonization flame and tungsten argon
arc welding for surfacing.Size:1.Normal diameter:2.7mm/3.2mm/4.0mm
2.Length:350mm; 500mm; 1000mm & 2000mm
