Low-alloyed Electrodes

ES 9018 D1 A5.5: E 9018-D1 / EN 1599: E Mo B 42

Description

ES 9018 -D1 is a basic coated electrode. AC/DC electrode for the welding of high tensile strength steels. It gives a weld metal that has good notch toughness down to - 60°C. Grain boundary cracking risk is very low.

Applications

Due to the weld metal's good notch toughness properties down to -60 C, it is used for welding unalloyed and low alloyed steel structures exposing to low temperatures like LPG holders. Welding of low alloyed high tensile steels when preheating cannot be applied and enclosed joint welding and cladding of rails when a hardness of about 250 HV is required are among its application areas.
