Welding electrodes Monolith M-318

AWS A5.4: E318-16
CSA W48:E318-16
EN ISO 3581-А-E 19 12 3 Nb R 1 2
Terms of use
  • electrodes are used for welding in all spatial positions, except vertical down one;
  • welding is recommended to be carried out at the highest possible speed without transverse oscilations of the electrode
Special properties
  • provide a seam metal that is resistant to intergranular corrosion;
  • characterized by high welding and technological properties: stable arc burning, easy slag removal, as well as good seam formation with a smooth
    transition to the base metal.
Мonolith М-318 electrodes are designed for welding corrosion-resistant austenitic Cr-Ni-Mo niobium stabilized steels, such as AISI 316Nb, AISI 316, AISI 318, etc., for parts operating at temperatures of up to 400°C (752°F). The electrodes are used for welding tanks, pipes and equipment for the chemical, textile, and paper industries in environments where acid, alkali, and salt solutions are found, as well as for constructions operating in seawater.
