Application/properties:
Rutile coated MMA electrode for welding stainless ferritic‐austenitic Cr‐Ni‐Mo steels (Duplex‐steel). Its weld metal
contains approximately 25‐35% delta ferrite. The high‐strength and ductile weld metal exhibits good resistance to
pitting, crevice corrosion and stress corrosion cracking in chloride‐bearing media. Fine metal droplet transfer, good
fusion of joint faces, finely rippled bead surface, easy slag removal, easy arc striking and restriking.
