Specification :

Oerlikon INOX 309Mo welding electrodes AWS SFA 5.4 : E 309Mo-16
Application & Properties:
Electrode for joining dissimilar steels (austenitic steels to ferritic steels) and for austenitic claddings. 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. Highest operating temperature for joints between dissimilar steels is +300oC. In case of higher temperatures, use OERLIKON SUPRANEL 600 electrodes. Fine metal droplet transfer, good fusion of joint faces, finely rippled bead surface, easy slag removal, easy arc striking and restriking.
