Classifications EN ISO 3581-A AWS A5.4 / SFA-5.4 E Z 18 9 MnMo R 3 2 E307-16 (mod.) Characteristics and typical applications Rutile-basic coated austenitic electrode of type E Z 18 9 MnMo R / E307-16 (mod.) for welding and cladding in all positions except vertical down. Versatile electrode for numerous applications – welding of "difficult-to-weld" steel grades, welding of different types as well as repair and maintenance. For hard buffer and intermediate layers for cladding of rails and switches, valve seats and in hydropower plants. The weld metal offers exceptionally high ductility and elongation together with outstanding crack resistance. Good resistance to embrittlement at service at service temperatures up to 650ºC. The weld metal work-hardens and offers good resistance to kavitation. The weld metal is resistant to scaling up to 850ºC, but at temperatures over 500ºC is that not sufficient resistance to sulfur-containing combustion gases. The weld metal offers high ductility, elongation and resistance to hot cracks, also after high fortynding of "difficult-to-weld" steel. Designed for first-class weld seams and easy handling on AC or DC. Ferrite according to WRC 92 is 4-8 FN. dissimilar joints, tough buffer layers and intermediate layers before hardfacing, 14Mn-steel, 13-17% Cr and heat-resistant Cr and austenitic steel up to 850ºC, armor plates, carbon-containing and hardened steel, surfacing of gears, valves, turbine blades etc. For welding of unalloyed/low-alloyed or Cr-steel with high-alloyed Cr- and CrNi-steel. Welding of austenitic highmanganesesteel and with other steel.
