DETAILS
CROMO E 225 is a basic coated 2,25%Cr-1%Mo electrode suitable for welding creep resistant steels like SA387 Gr22Cl1 and Cl2, A182F22, A336 F22, 10CrMo9-10 and similar. Core wire alloyed electrode. The weld metal chemistry is very low in tramp/impurity elements allowing to respect the Xbar (<12ppm) and J-factor (<120ppm) and showing excellent resistance to the step cooling test, no sensitive to the in-service embrittlement. Crack resistant and excellent tensile strength at high temperature and good creep rupture strength. Very low diffusible hydrogen (HD<4ml/100g).
