UTP A 2535NB MIG & TIG Welding Wire

The UTP A 2535NB MIG & TIG Welding Wire welding wire from Metals And Welding Specialities is a top-tier solution for precision welding applications that demand exceptional corrosion resistance and mechanical integrity. This high-performance filler metal is engineered for use in both MIG (Metal Inert Gas) and TIG (Tungsten Inert Gas) welding, offering outstanding results in joining dissimilar metals, overlay cladding, and repair welding. Classified under the UNS N06025 designation and corresponding to ASTM Grade ERNiCrMo-3, this alloy meets the highest international standards for nickel-chromium-molybdenum welding consumables.

Designed for reliability under extreme conditions, UTP A 2535NB provides a stable arc, smooth weld bead formation, and minimal spatter — attributes that make it a preferred choice among welding professionals working with Inconel, Hastelloy, and similar nickel alloys. Its universal standard name, EN ISO 18274: S Ni 6625 (NiCr22Mo9Nb), ensures compatibility across global welding practices and specifications. This filler wire is especially effective in joining alloys exposed to high temperatures, reducing environments, and corrosive chemical conditions, such as in the petrochemical, marine, and aerospace sectors.

One of the defining advantages of the UTP A 2535NB MIG & TIG Welding Wire wire is its resistance to intergranular corrosion and stress cracking. Its optimized chemical composition enhances performance in both oxidizing and reducing environments, maintaining weld strength and integrity even after prolonged exposure to harsh operating conditions. The addition of niobium (Nb) stabilizes the structure, preventing carbide precipitation during thermal cycling — a key factor for ensuring long-term durability in demanding service environments.

For industries where precision and consistency are non-negotiable, UTP A 2535NB delivers unmatched weld quality with superior metallurgical bonding. Its excellent wetting characteristics promote smooth transitions between weld passes, reducing post-weld finishing requirements. Whether used for process piping, pressure vessels, or heat exchanger fabrication, this wire ensures dependable results every time. The wire’s versatility extends to maintenance welding, where it performs equally well on worn components requiring overlay protection or dimensional restoration.

As part of the Metals And Welding Specialities premium product line, this welding wire is manufactured under strict quality controls to ensure purity, consistency, and traceability. Every spool is precision-wound for smooth feeding, ensuring optimum wire delivery in automated and manual welding systems alike. Trusted by professionals worldwide, UTP A 2535NB MIG & TIG Welding Wire sets a benchmark for weld integrity, corrosion resistance, and operational reliability — the qualities that define truly exceptional welding consumables.
