OK 63.30
SMAW
Type Rutile-acid
OK 63.30 is an extra-low carbon, LMA electrode of the 18Cr12Ni2.8Mo type. Also suitable for welding stabilized steels of similar composition except when the full creep resistance of the base material has to be met. OK 63.30 is very easy to strike and restrike and produces weld beads with an excellent appearance and self-relieving slag.
