Low-alloyed Electrodes

ES 9018 GN A5.5: E 9018-G / EN 757: E 55 6 1 NiMo B 45

Description

ES 9018-GN It is a basic coated Mo-Ni alloyed electrode with high ductile and crack resistance; for high strength fine grained steels. Suitable for service temperatures between - 60°C and + 350°C . Metal recovery approx. 115%. Easy to handle in all positions except vertical down. Preheating and inter pass temperatures, as well as post weld heat treatment as required by base metal. Deposits have very low hydrogen content. Re-drying is 300°C - 350°C min. 2 h.
