SFA-5.5
E 80 16-B2-H8
Application / Properties:
Electrode for welding of
creep resistant and
high-pressure hydrogen
resistant steels used in the
construction of pressure
vessels, boilers and piping
subjected to operating
temperatures up to +570°C. Owing to its double
covering (up to 3.25mmǾ),
the electrode shows a stable
and concentrate arc, thus
being well suited for root
pass and positional welding
. weld are of X-ray quality.
Preheating, inter pass
temperature and post-weld
heat treatment in accordance
with base metal to be
welded.
