Ultimate-80-B2:

Hydrogen controlled iron powder type electrode designed for welding creep-resisting Cr-Mo steels (0.5 Cr -0.5 Mo & 1 Cr- 0.5 Mo) and low alloy heat treatable steels. The weld metal displays excellent creep resistance at service temperatures upto 550°C.

Ease of operation in all positions.
Smooth and stable arc which is easy to strike & restrike, combined with low spatter and with due control on molten pool.
Slag detachability with little effort.
Finely rippled bead with regular profile.
Welds of consistent X-ray quality.
Weld metal which possesses excellent mechanical properties and displays resistance to cracking caused by heavy stresses and / or hydrogen.
A higher level of metal recovery at 100-110%.
Resistance to moisture pick-up.

Identification:Name Printed

Application:Welding of 1.25 Cr-0.5 Mo steel used for super heater tubes, steam pipes and headers of boilers for electric power plant, equipment of oil refineries.
