ESAB OK 68.82 VacPac welding electrodes

ESAB OK 68.82 – heavily alloyed ferritic-austenitic class stainless steel electrodes, with the weld metal containing 30–35% ferrite. The fused alloy is resistant to stress corrosion and is insensitive to dilution with the detail's alloy. Recommended working temperature up to 1150 °C. ESAB OK 68.82 electrodes are used when it is necessary to weld steels with poor weldability and for applying a buffer (underside) layer before hard welding. Also suitable for welding steels of unknown chemical composition, tensioning, pressing, and other tool repairs.
