Low-alloyed Electrodes

ES 8018 C1 A5.5: E 8018-C 1 / EN 499: E 46 8 2 Ni B 42 H5

Description

ES 8018 C1 is a heavily coated, Ni alloyed basic electrode. It is particularly useful for the welding of fine - grained steels and low alloy steels which have high impact resistance at low temperatures down to - 60 C. It is used for the welding of joints which need to have high toughness values at low temperatures. It gives a weld metal that has an excellent corrosion resistance to sea water and to sulphur acid fumes. It has about 120 % metal recovery. Good weldability in all positions except vertical down. Preheating and inter - pass temperatures as well as post weld heat treatment re-drying is 350°C - 400°C min. 2 h.
