Features and Applications

• Rutile type low carbon MMA electrode for joining dissimilar

steels (austenitic to ferritic steels) and for cladding of

austenitic steels. Weld metal consists of austenite with

approximately 15% delta ferrite. Cladding on unalloyed and

low-alloy steels are corrosion resistant in the first layer.
