ESAB OK 48.08

ESAB OK 48.08
Product Code: OK 48.08
Availability: In Stock

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