CHEM-WELD 2340

Electrode for stainless Cr-Ni-Mo steels

DIN 8556: E 19 12 3 LR 32

AWS A 5.4: E 316 L-17

Werkstoffnr.: 1.4430

E 1600: E 19 12 3 L R 32

Electrode with self removable slag. No spatter, quiet arc, soft flux, easy re-ignition, no ignition notches (highly polishable weld joint). High resistance to intergranular corrosion (low carbon content). Welding without cutting due to low electrode wetting, low heat input (welding at low currents). For welding joints and welds on stainless steels, for the chemical industry. E.g. for material CSN 17240,17249,17350, 17352, 17347, 17353, ferritic 13% Cr steels, mat. no. 1.4401, 1.4404, 1.4408, 1.4571, 1.4573, 1.4580, 1.4581. Suitable for boilers, tanks, scrubbers, oil tanks, fittings, for gas and water pipelines.
