OK 68.81 SMAW Type Rutile-acid OK 68.81 is a high-alloyed electrode which deposits a ferritic-austenitic duplex weld bbbbl with approx. 40% ferrite. Resistant to stress corrosion and highly insensitive to dilution. Good scaling resistance up to 1150�C. OK 68.81 is used for joining dissimilar steels, steels with reduced weldability and buffer layers prior to hardfacing. Applications: rolls, forging dies, hot-work tools, dies for plastics and so on. Welding current, A DC+, AC OCV 60 V |
