Ultimate-80:

Hydrogen controlled, basic-coated iron powder type electro Presence of Mn. & Ni. in appropriate proportion imparts to metal a high degree of low temperature notch toughne combined with high tensile strength. The electrode is thus suited for welding fine grained steels, Q&T steels, HSLA sterk used in Penstocks, Bridges, Pressure vessels, Tanks.

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.In particular, it displays remarkable impact resistance at subzero temperatures down to -60°C.
A higher level of metal recovery at 100-110%.
Resistance to moisture pick-up.

Notes on usage:

Redry the electrode at 300-350°C for one hour, cool them to 100°C and transfer them to a holding oven maintained at 50-60°C.
Minimise heat input and control interpass temperatures below 150°C to obtain optimum impact values.
Clean the weld area free of any surface contaminations.
