Haynes C-22/122 description: HAYNES 122 coated electrodes are used for the shielded metal arc welding of C-22, 622, 625 and 825 alloys. The electrodes are also a good candidate for welding stainless steels that contain molybdenum for corrosion resistance. The alloy also eff ectively overmatches alloys 625 and C-276. The electrodes have a slag system that promotes great operability in all positions, especially out-of-position welding.
