Low-alloyed Electrodes
ES 8018 B6 A5.5: E 8018-B6 / EN 1599: E CrMo5 B 42 H5
Description
ES 8018 B6 Basic coating electrode for the welding of steel at high temperature and applications containing high levels of hydrogen. Preferably used for the welding of X12CrMo5 (5CR 0.5Mo) steel. Approved to be used in long-term applications in service temperatures of up to 650ºC. High resistance to cracks, very low contents of hydrogen (according to AWS regulation, HD ?4ml/100g of welding metal). Good weldability in all welding positions, except descending vertical. The base metal is thermally treatable. Metallic yield of about 115%. Redrying temperature, 350°C, Redrying time, 2 hours, Recovery 115%
