What is Hastelloy C-22/122 Coated Electrodes?

Nickel (about 56%) makes up the majority of Hastelloy C-22/122 Coated Electrodes, with notable additions of chromium (20–22.5%), molybdenum (12.5–14.5%), iron (2–6%), and trace amounts of cobalt, tungsten, and manganese. Superior resistance to oxidising and reducing environments is provided by this alloy. The deposited weld metal usually maintains exceptional ductility and impact toughness while achieving tensile strengths above 90,000 psi. Even in difficult welding positions and environmental circumstances, the electrodes’ smooth arc transfer, low spatter, and simple slag removal ensure excellent welds with robust metallurgical integrity.
