ยี่ห้อ : Castolin Eutectic

รุ่น : EutecTrode® Xuper NucleoTec 2222

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 & non-ferrous metals in dissimilar combinations eg. carbon / high alloy / stainless steels, various nickel & 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
