Description & applications

Rutile-basic coated electrode Niobium (Columbium) - stabilised 18Cr 12Ni 3Mo austenitic stainless steel deposit with approx. 8% delta ferrite. The electrode is suited to weld Ti or Nb (Cb) stabilised CrNiMo austenitic stainless steels. Soft fusion without spatters, easy strike and restrike, in most cases self peeling slag, moisture resistant coating. Deposit resistant against intercrystalline corrosion, and highly corrosion resistant against different attacks. Used for service temperatures from -120°C up to +400°C in petrochemical industries and for sea water applications, refineries, tanks, heat exchnagers...
