Product Overview

ERNiCrMo-3 Nickel Alloy Welding Wire is a high-performance solution crafted to fulfill the highest quality standards, setting a new benchmark in industrial welding. Renowned for its exceptional mechanical properties and versatility, it is the preferred choice for professionals across a broad spectrum of industries.

1. Chemical Composition Precision-controlled elements: Nickel (Ni: 58-62%), Chromium (Cr: 20-23%), Molybdenum (Mo: 8-10%), and Niobium (Nb: 3.15-4.15%). Low impurities (Fe ≤1.0%, S ≤0.02%, P ≤0.015%) minimize cracking risks.

2. Mechanical Properties High tensile strength (≥760 MPa) and yield strength (≥420 MPa). Exceptional elongation (≥27%) and impact toughness for both cryogenic and high-temperature stress resistance.

3. Physical Properties Density: 8.4 g/cm³. Melting Range: 1290-1350°C. Stable Ni3(Nb,Ti) phases post-heat treatment ensure structural integrity.

4. Key Features Outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking in chloride, acidic, and marine settings. Oxidation resistance up to 1800°F (982°C).

Applications & Compatibility

Industry Integration Indispensable for Aerospace (engine components), Chemical Processing (reactors, pipelines), Marine (valves, seawater systems), and Oil/Gas (wellhead equipment).

Material Welding Effortlessly welds INCONEL 625, INCOLOY 825, 20alloy, 9% Ni steel, and dissimilar metal combinations such as carbon steel to nickel alloys.

Welding Methods Compatible with TIG (GTAW), MIG (GMAW), SAW, and Plasma Arc. Recommended shielding: Argon or Argon-Helium mixtures.
