Properties And Applications

Rutile type, high recovery (160%) stainless steel electrode for welding dissimilar steels ferritic to austenitic steels and depositing austenitic stainless claddings. The austenitic weld metal has a delta-ferrite content of approx. 15 %. Claddings on unalloyed steels are already corrosion resistant in the first layer, due to Mo (molibdenum) content. Highest operating temperature for dissimilar steel joints is +300°C. Possible to use equally well both with AC and DC. Easy arc striking and re-striking. Fine metal droplet transfer, good fusion of joint faces, finely rippled bead surface, easy slag removal. High current carrying capacity, since core wire is not made of stainless steel.
