Type Acid Rutile
Supplied in 1.7kg pack
OK 68.81 is a high-alloyed electrode which deposits a ferritic-austenitic duplex weld metal with approx. 40% ferrite. It is resistant to stress corrosion and is highly insensitive to dilution. Good scaling resistance up to 1150°C. OK 68.81 is used for joining dissimilar steels, steels with reduced weld ability and buffer layers prior to hard facing. Applications: rolls, forging dies, hot-work tools, dies for plastics and so on.
Welding current
DC+, AC OCV 60 V
