OK 68.81 SMAW Type Rutile-acid OK 68.81 is a high-alloyed electrode which deposits a ferritic-austenitic duplex weld bl 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 |
