EN ISO CODE:
D&H 430Nb is a rutile coated electrode depositing 17%Cr-1%Nb. The weld metal is a ferritic microstructure with fine grains for welding of similar chrome steels and steel castings. The weld metal shows good corrosion resistibility and good oxidation resistibility. This electrode requires suitable post and preheats treatment for obtaining optimum weld metal properties. The welds are of radiographic quality. It is also suitable for first layer in the welding of type 405 and 410 clad steels. Typical applications include machine parts, propeller shafts, gas turbine construction, pump parts components in oil refineries, etc.
