Product Description

ERNiCr-3
This Ni base alloy solid welding wire, known as ERNiCr-3, boasts exceptional resistance to cracking, especially ductility dip cracking in weld metal. It significantly enhances the tensile strength of the weld metal, ensuring it meets or surpasses the tensile strength of the base material. In addition, it offers unmatched weldability, making it a preferred choice for high-stakes welding applications.

1. Basic Specifications & Composition
Standards Compliance:
AWS A5.14: ERNiCr-3
DIN: SG-NiCr20Nb (Werkstoff Nr. 2.4806)
ISO/BS: SNi6082 / NiCr20Mn3Nb.
Chemical Composition:
Element Content (%) Role
Nickel (+Cobalt) ≥67.0 (72.9 typical) This base metal composition guarantees superior corrosion resistance.
Chromium 18.0-22.0 Provides outstanding oxidation resistance.
Niobium (+Tantalum) 2.0-3.0 Plays a crucial role in preventing intergranular corrosion by stabilizing carbides.
Manganese 2.5-3.5 Enhances toughness while minimizing the risk of hot cracking.
Iron ≤3.0 Maintains impurity control at optimal levels.
Carbon ≤0.10 Reduces carbide precipitation effectively.
Sulfur/Phosphorus ≤0.015/≤0.030 Essential in diminishing brittleness.
2. Key Properties
Mechanical Performance:
Tensile Strength: ≥552 MPa (80,000 psi) Delivers remarkable strength and reliability.
Elongation: ≥30% (4d) Ensures material flexibility and resilience.
High-Temperature Capabilities:
Operating Range: -196°C to +550°C Ideal for pressure vessels with extensive temperature demands. Shows exceptional oxidation resistance in sulfur-free environments, capable of withstanding up to 1200°C.
Creep Rupture Strength: Demonstrates superior performance under sustained thermal stress.
Corrosion Resistance:
Offers robust resistance against oxidation, stress corrosion cracking, and pitting in harsh acidic environments, such as sulfuric, phosphoric, and urea.
3. Welding Applications
Compatible Alloys:
Nickel Alloys: Ideal for INCONEL 600/601/690 and INCOLOY 800/800HT/330.
Dissimilar Metal Joints
Nickel alloys Carbon steel/stainless steel
INCOLOY 330 MONEL alloys.
Surface Cladding:
Perfect for creating corrosion-resistant overlays on carbon steel components.
Process Compatibility:
Compatible with TIG/GTAW, MIG/GMAW, and Submerged Arc Welding (SAW) processes.
SAW Flux Pairing: Optimal pairing with INCOFLUX 4 (NI-ROD 99 wire), allowing ≤3 layers with INCOFLUX.
4. Industry Use Cases
Aerospace: Perfect for turbine blades and combustion chambers, offering high-temperature oxidation resistance.
Nuclear: Ideal for reactor vessels and fuel piping, providing creep strength in radiation-intense environments.
Chemical Processing: Optimal for reactors and heat exchangers due to its acid corrosion resistance.
