Comparable No. of materialApplication/properties:
Basic electrode for joining of dissimilar steels, (austenitic steels to ferritic steels) and for depositing claddings austenitic. Weld metal consists of with approximately 15% delta-ferrite. Claddings on alloyed or low-alloyed steel are already corrosion resistant in the first layer. Highest operating temperature for dissimilar steel joints is +300°C; at higher temperature AMA 1604G electrode shall be used. The electrode has a stable arc.
