CROMOTHERME-2(MOD)
AWS: SFA 5.5 E9018-B3
EN ISO CODE: 3580-A E CrMo2 B 4 2 H5
A low hydrogen iron powder electrode depositing 2.25Cr -1Mo weld metal having o low level of impurities and exhibiting excellent toughness up to -18 C. Weld metal retains its mechanical properties even after prolonged heat treatments. Ideal for welding steels of similar composition to achieve tough weld metals.
