Product Description

ERNiCrFe-1 is a nickel-based welding wire classified under the Ni-Cr-Fe alloy system, widely used in high-temperature and corrosive environments. Below is a comprehensive technical description based on current standards and industrial practices:

1. Chemical Composition

Key elements (typical wt% range):

Nickel (Ni): 70-75% (base metal, ensures corrosion/heat resistance).

Chromium (Cr): 14-17% (enhances oxidation and pitting resistance).

Iron (Fe): 6-10% *(Note: Some sources list Fe ≥22% for ERNiFeCr-1 variants; verify specification)*.

Trace Elements:

Manganese (Mn) ≤1.0%, Silicon (Si) ≤0.5% (deoxidizers).

Molybdenum (Mo) 2.5-3.5%, Titanium (Ti) 0.6-1.2% (crack resistance).

Carbon (C) ≤0.05%, Sulfur (S) ≤0.03% (minimize hot cracking).

2. Key Properties

Mechanical Performance :

Tensile Strength: ≥550 MPa (room temperature).

Elongation: ≥30% (excellent ductility).

Functional Advantages:

Temperature Resistance: Stable at 600-900°C, resists creep and oxidation.

Corrosion Resistance: Withstands sulfuric/nitric acids, alkaline media, and stress-corrosion cracking.

Weldability: Low crack sensitivity; suitable for TIG (GTAW), MIG (GMAW), SAW processes.

3. Standards & Certifications

Complies with international specifications:

AWS A5.14/ASME SFA-5.14 (U.S.) .

ISO 18274:2010 (Global) .

GB/T 15620 (China).

4. Welding Parameters

Optimal conditions for common methods :

Process Wire Diam. (mm) Current (A) Voltage (V) Protective Gas

GTAW/TIG 1.6 90-130 14-18 100% Ar (99.99% purity)

GMAW/MIG 1.2 180-220 28-32 Ar + 25% He (75:25 mix)

Critical Controls:

Interpass Temp.: <150°C to avoid grain coarsening.

Gas Flow Rate: 10-15 L/min to prevent porosity.

Post-Weld Heat Treatment: Not usually required; stress relief at 600-650°C for thick sections.
