OK 68.82 is a high-alloyed electrode which deposits a ferritic-austenitic duplex weld metal with approx. 30-35% ferrite. It is resistant to stress corrosion and is highly insensitive to dilution. Good scaling resistance up to 1150°C. OK 68.82 is used for joining steels with reduced weldability and buffer layers prior to hard surfacing, dissimilar steels, rolls, aluminium-forging dies, hot-work tools, dies for plastic and so on.
