Ultimate-70-B2L:

Hydrogen controlled iron powder type electrode designed for welding creep-resisting 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, when the job requirement calls for carbon in weld metal to be controlled at 0.05% or less. Moreover, S & P levels are kept low to improve ductility & toughness.
