Properties And Applications

Rutile type electrode for joining dissimilar steels (austenitic steels to ferritic steels) and for austenitic claddings on ferritic steels. Weld metal consists of austenite with approx. 15% delta-ferrite. Claddings on unalloyed and low alloy steels are already corrosion resistant in the first layer. Higher operating temperature for joints between dissimilar steels is 300°C. Fine metal droplet transfer, good fusion of joint faces, finely ripped flat and smooth bead surface, especially in fillet welds. Easy slag removal of slag.
