SAF Lexal E 22 9 3 N description: LEXAL E 22 9 3 N is a rutile coated MMA electrode, with homogeneous Duplex core wire, for welding
ferritic-austenitic duplex stainless steels, e.g.1.4462 and UNS S31803, also for joining duplex to standard austenitic or ferritic steels. The weld metal has high-strength, toughness and good resistance to pitting, crevice and stress-corrosion cracking in media containing chlorides and hydrosulphides. Weld metal transfer is in fine droplets, good fusion of the joint faces, easy slag removal and finely rippled bead surface. Maximum operating temperature<250C.
