Description and application:
Basic, CTOD tested electrode with excellent welding characteristics, recommended for welding structural steels and
steel castings with tensile strength up to 610 N/mm2 and finegrained steels with increased yield strength.
Metal recovery is about 118 %. Deposits have very low hydrogen contents (HD < 4 ml/100 g).
