Cobalt based Welding Rod

This series of Co-Cr-W based hardfacing electrodes cover classic grades Stellite 6, 12 and 21, available in bare cast rod and coated electrode types.
Bare cast rods fit oxy-acetylene welding, TIG and PTA hardfacing with dense pure deposits for precision workpiece processing. Coated electrodes suit manual arc welding without extra shielding gas, enabling flexible on-site repair for large workpieces.
Each grade has targeted performance: Stellite 6 features balanced wear, corrosion and thermal fatigue resistance; Stellite 12 delivers higher hardness for heavy wear conditions; Stellite 21 boasts superior toughness, corrosion resistance and thermal shock performance. Widely applied to valves, pumps, forging dies, oil tools and rolling mills, they effectively extend workpiece service life under complex conditions.
