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.
