CROMOTHERME-20 Mo

AWS: SFA 5.5 E9018-G

EN ISO CODE:

Cromotherme-20Mo is a low hydrogen iron power type electrode yielding a weld deposit containing 1.25 Cr - 1.0 Mo - 0.25 V. The electrode produces stable and steady arc, easy striking and re-striking. The slag is easily detachable. The welds are of radiographic quality. Ideal for welding Cr – Mo - V steels of similar compositions, filling up work on alloy castings of similar compositions e.g. GS17CrMoV510. The weld metal possesses excellent room temperature and elevated temperature properties.
