China Stellit 12 Rod Hardfacing Welding Cobalt Base Welding Electrode

Product Name: Stellite 12 cobalt-based cast rod/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.
Welding method:
use oxygen-acetylene carbonization flame and tungsten argon arc welding for surfacing.
