Welding Electrode E BK 9018 B3  

E BK 9018 –B3  , is a Cr-Mo alloyed electrode for joining heat resistant steels with a chromium content of approx. 2.5 % and a molybdenum content of approx.1.2 %. The deposit is heat resistant up to 600 °C (1110 °F). Good welding properties, also in position. low-hydrogen electrodes producing weld metal that nominally contains 1.25% Cr and 0.5% Mo.  They are designed to produce weld metal for high temperature service and for matching the properties of some chromium-molybdenum base materials such as ASTM A387 Grade 11.  Since all chromium-molybdenum electrodes produce weld metal which will harden in still air, both preheat and PWHT are required for most applications. E8018-B2 has quick and easy slag removal, which reduces clean up time.  The low spatter level improves weld bead appearance and lends itself to higher depositions. Field of application up to operational temperatures of 550 °C.
