SAF Safer MD 56 description: SAFER MD 56 is a low-alloyed basic coated MMA electrode with a low hydrogen content. For welding low alloyed and fine grain steels with a high yield strength <550 Mpa such as creep resistant manganese an molybdenum steels. This electrode is also recommended when good as-welded impact strengths at low temperatures are required. The SAFER MD 56 is used in all on- and offshore, gas and pipeline applications with a higher yield strength <550 Mpa , down to -50C. 120% efficiency. Easy striking.
