Product Description

ERNiCr-3
Experience unparalleled welding excellence with our Ni base alloy solid welding wire. Renowned for its superb resistance to ductility dip cracking, it significantly enhances the tensile strength of weld metal, matching or surpassing that of the base material itself. Combining outstanding weldability, our wire is your go-to choice for premium welding results.

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
Ni (+Co) ≥67.0 (72.9 typical) Serving as the base metal, it provides robust corrosion resistance.
Cr 18.0-22.0 Offers superior oxidation resistance.
Nb (+Ta) 2.0-3.0 Essential for preventing intergranular corrosion through carbide stabilization.
Mn 2.5-3.5 Enhances toughness and minimizes hot cracking.
Fe ≤3.0 Stringent impurity control.
C ≤0.10 Reduces carbide precipitation, ensuring durability.
S/P ≤0.015/≤0.030 Key to decreasing brittleness.
2. Key Properties
Mechanical Performance:
Tensile Strength: An impressive ≥552 MPa (80,000 psi), guaranteeing reliability.
Elongation: ≥30% (4d), offering flexibility and resilience.
High-Temperature Capabilities:
Operating Range: From a chilling -196°C to a hot +550°C, perfect for pressure vessels. Withstands oxidation up to 1200°C in sulfur-free environments, providing safety and longevity.
Boasts excellent creep rupture strength under continuous thermal stress.
Corrosion Resistance:
Exhibits resistance to oxidation, stress corrosion cracking, and pitting in harsh acids like sulfuric, phosphoric, and urea environments.
3. Welding Applications
Compatible Alloys:
Effortlessly welds with Nickel Alloys such as INCONEL 600/601/690, and INCOLOY 800/800HT/330.
Dissimilar Metal Joints
