AWS A5.5 / ASME SFA5.5 E9015-B9
JIS Z3223 E6215-9C1MV
EN 1599 ECrMo91 B 4 2 H5
Notes on Usage
Welding Positions:
① Dry the electrodes at 350~400℃(662~752℉) for 60 minutes before use.
② Preheat at 200~315℃(400~600℉) and postheat at 750~770℃(1382~1418℉).
③ Adopt back step method or strike the arc on a small steel plate prepared for this particular purpose to prevent blow hole at the arc starting.
Applications
AWS A5.5 / ASME SFA5.5 E9015(6)-G H4 can be used for Welding of 9%Cr-0.5%Mo-1.5%W heat resistant steel. Used for pipes of boilers for power plant, equipment for oil refining industries, and high temperature synthetic chemical industries.
