0.8mm 1.0mm 1.2mm 1.6mm ERNiCrMo-3 Welding Wire Corrosion Resistance
High-Performance ERNiCrMo-3 Welding Wire – Corrosion Resistance for Extreme Environments
Description
ERNiCrMo-3 welding wire is a nickel-chromium-molybdenum alloy designed for welding applications requiring exceptional resistance to corrosive media, high-temperature oxidation, and stress corrosion cracking. With a composition of 58% nickel, 22% chromium, and 9% molybdenum, this filler metal delivers robust performance in aggressive environments such as sulfuric acid, phosphoric acid, and chloride-rich settings. Its low carbon content (≤0.05%) minimizes carbide precipitation, ensuring weld integrity in temperatures up to 550°C (1,022°F).
Ideal for joining dissimilar metals like Inconel 625, Hastelloy C-276, and stainless steels, ERNiCrMo-3 wire complies with AWS A5.14 and ASME SFA-5.14 standards. The alloy’s high ductility (≥30% elongation) and tensile strength (≥760 MPa) prevent cracking in dynamic or cryogenic applications, including offshore platforms, chemical reactors, and flue gas desulfurization systems. Its low thermal expansion coefficient (13.1 µm/m·°C) ensures dimensional stability in cyclic thermal operations.

Q&A
Q1: Can ERNiCrMo-3 wire weld dissimilar metals like stainless steel to nickel alloys?
A: Yes. Its balanced composition ensures strong, crack-free joints between austenitic steels, nickel alloys, and duplex steels.
Q2: Is post-weld heat treatment necessary for ERNiCrMo-3 welds?
A: Generally not required due to low carbon content, but stress-relief annealing (650–870°C) is recommended for thick sections.
Q3: Does the wire comply with NACE MR0175 for sour service?
A: Yes. ERNiCrMo-3 meets NACE standards for H₂S-resistant applications in oil and gas environments.
