Stainless and heat resistant steels electrode Oerlikon SUPRANOX 309L Ø3.2x350 mm

SUPRANOX 309L is a rutile coated MMA electrode for joining dissimilar steels, austenitic steels to ferritic steels, and for stainless cladding. The weld metal microstructure is austenite with ~15 % delta-ferrite.

Cladding on unalloyed and low-alloy steels is corrosion resistant in the first layer. Metal transfer is in fine droplets, good wetting of the joint faces, finely-rippled weld bead surface, easy slag removal with good striking and restriking. The maximum operating temperature for dissimilar joints is 300 °C, for higher temperatures or postweld heat treatments use SUPRANEL 600. One package contains approximately 120 pieces. The weight of the package is 4.3 kg.
