Xuper Nucleotec 2222 Welding Electrodes

At Metals And Welding Specialities, we are proud to present the Xuper Nucleotec 2222 Welding Electrodes, a high-performance welding consumable engineered for the most demanding fabrication and repair tasks. This specialized electrode offers exceptional crack resistance, high ductility, and superb corrosion resistance across a wide temperature range. Designed for joining dissimilar materials and tackling challenging steel grades, the Xuper Nucleotec 2222 excels in applications where standard electrodes fall short.

The Xuper Nucleotec 2222 electrode features a nickel-chromium-manganese alloy core, whose weld deposits resist grain boundary embrittlement and σ-phase formation, maintaining toughness at low temperature and stability under cyclic thermal loads. Its universal usability in all welding positions permits flexibility in layout and orientation. Under classification systems, it is identified under EN ISO 14172 as E Ni 6182, and under AWS standards corresponds to E NiCrFe-3 (sometimes referenced as an equivalent to CEWELD E NiCro 600). The material number (W. Nr.) for its nickel alloy formulation is 2.4807, and the equivalent UNS designation is UNS N06600 (or associated Ni-Cr-Fe classes)

In terms of mechanical performance, the Xuper Nucleotec 2222 deposit reliably achieves tensile strength in the 90,000–100,000 psi range (approximately 620–690 MPa) with elongation up to 45 % and excellent impact toughness even at subzero conditions. Because the weld metal matches its base in toughness and lacks harmful phases, it is ideal for critical structural joins, cryogenic equipment, heat exchanger assemblies, kiln tires, chemical plant components, and injection molds, where thermal cycling and stress concentration are frequent challenges

With its optimized alloy composition, Xuper Nucleotec 2222 delivers excellent bonding characteristics on both carbon and alloy steels. Its weld deposits exhibit superior crack resistance, allowing for stress-free performance under thermal fatigue and shock loads. This makes it a preferred choice for critical components such as kiln tires, crusher rolls, exhaust manifolds, furnace parts, and rotary kilns. Each electrode is precision-manufactured to meet stringent quality standards, guaranteeing uniform deposition and predictable results for professional welders.

By choosing the Xuper Nucleotec 2222 electrode from Metals And Welding Specialities, clients gain the assurance of a premium nickel alloy welding solution, backed by material integrity, dimensional stability, and seamless performance under thermal cycling. Whether your project involves heavy section welds, repair of critical equipment, or dissimilar material joints, this electrode offers the durability, strength, and corrosion resistance your operations demand. Trust in this product to deliver X-ray quality welds, minimal distortion, and a weld metal that holds up where conventional electrodes cannot.
