Castolin EutecTrode Xuper NucleoTec 2222 description:
Low heat input, high nickel based alloy manual electrode
Features and benefits
With proprietary formulation for maximum safety margin welding crack repairs on thick section parts of low alloy or air-hardenable steels.
Also developed for safe, reliable joints between ferrous and non-ferrous metals in dissimilar combinations eg. carbon / high alloy / stainless steels, various nickel and copper based alloys.
Reliable weld metallurgical properties retained from cryogenic to refractory temperatures
Unique plastic ductility properties minimise harmful residual stresses and distortion
Exceptional resistance to fatigue cracks caused by stress raisers or thermal cycles
Coefficient of thermal expansion similar to steel reduces welding stresses
Maximum resistance to hydrogen induced cold cracking defects
Highest dilution tolerance for Fe, Cr, Ni, Mn, C, Cu
Thermal shocks do not embrittle the weld deposit structure
Suitable for service in corrosive or high temperature environments
Economises costly preheating and Post Weld Heat Treatment procedures
