LOW HYDROGEN ELECTRODES
OK 48.08
Type: Basic SMAW E7018-G
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 -60°C. The coating is of the latest LMA type for optimum resistance to porosity and
hydrogen cracking. OK 48.08 is CTOD tested.
