OK 61.30
SMAW
Type Rutile-acid
OK 61.30 is an extra-low carbon, AC/DC, LMA electrode for welding steel of the 19Cr10Ni type, also suitable for welding stabilized stainless steels of similar composition, except when the full creep resistance of the base material is to be met. OK 61.30 is very easy to strike and restrike and gives weld beads with excellent appearence and self-relieving slag.
