OK 48.08
SMAW
Type Basic

OK 48.08 is an LMA electrode with very good mechanical properties suitable for demanding applications, e.g. offshore. The weld metal contains approximately 1% Ni for high impact values down to -40C. The coating is of the latest LMA type for optimum resistance to porosity and hydrogen cracking. OK 48.08 is CTOD tested.
