China Cobalt Based Hardfacing Rod Co6 Rod Grade 6 TIG Rods

Cobalt based hardfacing rod Co6 rod grade 6 TIG rods
Product Name: Stellite12 cobalt-based cast rod
Zander.welding.industry Specifications: 3.2mm, 4.0mm, 4.8mm, length 1000mm
Standard: AWS A5.21:2001 ERCoCr-B
Note: 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.
