Esab OK 68.81 4.0x350mm 1/2 VP Allmat 312L 68814030G0
ESAB 6881 ALLMAT is an acid-rutile, high-alloyed electrode which deposits a ferritic-austenitic duplex weld metal with approx. 40% ferrite. Resistant to stress corrosion and highly insensitive to dilution. Good scaling resistance up to 1150 degrees 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 etc. Welding current DC+, AC, OCV 60 Volts
