Product Description
ERNiCrMo-4 is a premium nickel-chromium-molybdenum solid welding wire compliant with AWS A5.14/A5.14M standards, designed for Hastelloy C-276 (UNS N10276) and similar nickel-chromium-molybdenum alloys. Featuring a high-purity composition with 15.0-17.0wt.% molybdenum, 14.5-16.5wt.% chromium, and strict impurity control (C≤0.02wt.%, Si≤0.08wt.%), it excels in severe corrosive environments with oxidizing and reducing media. Compatible with GTAW (TIG) and GMAW (MIG) processes, it supports welding of homogeneous nickel-chromium-molybdenum alloys, dissimilar metal joints (nickel alloys to steel/stainless), and corrosion-resistant surfacing/cladding applications.
Features
▪ Superior Corrosion Resistance: Offers exceptional resistance to chloride-induced pitting, crevice corrosion, and stress corrosion cracking (SCC) in seawater and acidic environments. The high molybdenum and tungsten content provides outstanding protection against oxidizing acids (nitric, sulfuric, phosphoric) and mixed media containing chlorides/H₂S.
▪ Stable Performance: Low-carbon design (C≤0.02%) minimizes carbide precipitation during welding, maintaining corrosion resistance in as-welded structures without post-weld heat treatment. Weld metal exhibits tensile strength of 790-830MPa, elongation ≥27-42%, and excellent toughness from cryogenic to elevated temperatures, matching base material properties.
▪ Excellent Weldability: Ensures smooth weld formation with good slag removal and arc stability. Compatible with DCEN (GTAW) and DCRP (GMAW) modes, it adapts to various welding positions with flexible shielding gas options (100% Ar for TIG, 75%Ar/25%He for MIG). Suitable for normal-to-medium temperature welding with proper interpass temperature control.
Applications
▪ ERNiFeCr-1 is widely utilized in industries where reliable corrosion resistance is paramount:
▪ Chemical & Petrochemical Industry: Used for reactors, heat exchangers, and piping systems handling sulfuric acid, phosphoric acid, and organic acids.
▪ Oil & Gas Sector: Ideal for acid oil and gas treatment equipment, pipelines, and components exposed to sour environments.
▪ Environmental Protection: Applied in flue gas desulfurization (FGD) systems and acid wastewater treatment facilities.
▪ Industrial Manufacturing: Used in pickling tanks, paper manufacturing bleaching equipment, and pollution control systems.
