Product Description
ERNiCrMo-3 Welding Wire (Inconel 625 / UNS N06625)
Corrosion-resistant nickel alloy filler metal for extreme environments, suitable for TIG (GTAW) and MIG (GMAW) welding processes.
Product Description
ERNiCrMo-3 is a solid nickel-chromium-molybdenum alloy welding wire used for welding Inconel 625 and similar corrosion- and heat-resistant alloys. This filler metal offers exceptional resistance to pitting, crevice corrosion, intergranular attack, and stress corrosion cracking in severely corrosive environments including seawater, acids, and oxidizing/reducing atmospheres.
Widely used for both overlay cladding and joining applications in industries such as chemical processing, marine, power generation, and aerospace.
Key Features
- Exceptional resistance to seawater, acids (H₂SO₄, HCl, HNO₃), and high-temperature oxidizing/reducing atmospheres
- Excellent pitting and crevice corrosion resistance in chloride-rich environments
- Outstanding weldability with smooth arc, minimal spatter, and clean bead appearance
- Maintains mechanical strength up to 980°C (1800°F)
- Highly resistant to stress corrosion cracking and intergranular corrosion
- Ideal for dissimilar metal welds, overlays, and hardfacing
- Conforms to AWS A5.14 ERNiCrMo-3 and UNS N06625
