OK 68.82 SMAW
Type Acid-rutile (E312-17)
Description
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 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 diies, hot-work
tools, dies for plastic and so on.
