Cobalt Based Co12 Welding Rod
Cobalt Based Co12 Welding Rod Introduction: Standard type,generally used in valve industry,Oxy-acetylene or TIG process,wear-resistance,anti-corrosion, especially in high temperature ambient
Co12 could be considered an intermediate alloy between Co6(Stellite6) and Co1(Stellite1). It contains a higher fraction of hard, brittle carbides than Co6(Stellite6), and has increased resistance to lowangle erosion, abrasion, and severe sliding wear whilst retaining reasonable impact and cavitation resistance. Co12 is often used self-mated or running against Co6(Stellite6) or Co1(Stellite1). The higher tungsten content provides better high-temperature properties compared to Co6(Stellite6), and it can be used at temperatures up to about 700˚C. Co12 is typically used for cutting tools that need to withstand abrasion, heat and corrosion. Examples include industrial knives for cutting carpets, plastics, paper and synthetic fibres; and saw tips in the timber industry. It is also used for control plates in the beverage industry, pump vanes, bearing bushes and narrowneck glass mold plungers; and for hardfacing of engine valves, pinch rollers in the metal-processing industries, and rotor blade edges.
OXY Or TIG
Used most in engine valve industry.
Composition uniformity, segregation-free,
Low impurity content; good liquid flowability,
Low porosity, good manufacturability;
Minimum diameter tolerance, fine effect surface,
The length can be tailored.
