Description:

P 65MR is a basic-coated low hydrogen electrode producing a nominal 0.9% Ni weld metal with

molybdenum addition, designed for welding steels with a minimum yield strength of 450 MPa e.g. BS

7191-450 EM, BS 4360-55E/F and similar materials, used in offshore fabrication etc.

P 65MR gives a minimum yield strength of 560 MPa, minimum tensile strength of 610 MPa and has

excellent fracture toughness down to -60 °C. It is an AC/DC, all-positional electrode producing a finely

rippled bead surface and good slag detachability. Electrode sizes 3,2x350 mm also available with a

thin coating, "tc", ideally suited for root pass welding and joints with restricted access.
