Low-alloyed Electrodes
ES 8018 C2 A5.5: E 8018-C 2 / EN 499 : E 46 8 3 Ni B
Description
ES 8018 C2 It is a Ni alloyed basic coated electrode. It gives a Ni alloyed weld metal that is particularly useful for the welding of fine - grained steels and low alloy steels which have high impact resistance at low temperatures down to - 110 °C. Ductile and crack resistant metal deposit. Very low hydrogen content ( < 5 ml / 100 g. ). Easy handling in all position except vertical down. Preheating and inter-pass temperatures, as well as post weld heat treatment as required by base metal. Efficiency is approximately % 120. Re-drying is 350°C - 400°C min 2 h.
