Notes on Usage
Welding Positions:
① Dry the electrodes at 350~400℃(662~752℉) for 60 minutes before use.
② Preheat at 200~350℃(392~662℉) and postheat at 670~730℃(1256~1346℉).
③ Keep the arc as short as possible.
Applications
AWS A5.5 / ASME SFA5.5 E9018-B3R can be used for Welding of 2.25%Cr-1%Mo heat resistant steel. Used for steam pipes of boilers for power plant and marine use, equipment for oil refining industries, and high temperature synthetic chemical industries.

Characteristics on Usage
AWS A5.5 / ASME SFA5.5 E9018-B3R is an iron powder low hydrogen type electrode. Its coating contains much iron
powder, which increases working efficiency. Relevant trace element P, Sn, As and Sn are
controlled to ensure low X-Factor. (X-Factor ≤ 15ppm) Its usability is good with direct current
applications and very low-hydrogen electrode. (HDM ≤ 5ml/100g) Good toughness against the
impact value at low temperature.
