Product Description
ERNiCrMo-14 is a high-alloy nickel-chromium-molybdenum solid welding wire compliant with AWS A5.14/A5.14M standards, specifically designed for the most severe corrosive environments.It features a robust composition with nickel as the remainder, 19.0-23.0wt.% chromium, 15.0-17.0wt.% molybdenum, and 3.0-4.4wt.% tungsten.This filler metal is compatible with GTAW (TIG), GMAW (MIG), and Submerged Arc Welding (SAW) processes.It is an exceptional candidate for welding duplex, super-duplex, and super-austenitic stainless steels, as well as high-performance nickel alloys such as Alloy 686, C-276, and Alloy 22.It is also widely used for depositing overlays of outstanding corrosion resistance onto a range of carbon and low-alloy steels.
Features
▪ Unmatched Corrosion Resistance in Aggressive Media: ERNiCrMo-14 offers the highest level of resistance among Ni-Cr-Mo alloys to a wide variety of chemical process environments.Its high content of Cr, Mo, and W results in increased resistance to pitting, crevice corrosion, and general corrosion, particularly in hydrochloric or sulfuric acid services.
▪ Superior Resistance to Localized Attack: This alloy demonstrates exceptional resistance to crevice corrosion in hot, concentrated acid chloride solutions, such as sulfur dioxide, saturated NaCl solutions, and oxidizing chloride solutions.It also maintains high resistance to intergranular attack after sensitization in highly oxidizing environments.
▪ Excellent Weldability and Thermal Stability: ERNiCrMo-14 is readily weldable and typically requires no post-weld heat treatment to restore its full corrosion resistance.Its precise chemical balance ensures stable performance and high-quality weld deposits in both manual and automated welding processes.
Applications
▪ ERNiCrMo-14 is utilized in the most demanding industrial and environmental sectors:
▪ Chemical Processing: Used for reactors, heat exchangers, and piping systems handling highly aggressive oxidizing and reducing acids.
▪ Pollution Control: Ideal for flue gas desulfurization (FGD) systems, including scrubbers, reheaters, and fans exposed to corrosive gases.
▪ Marine Engineering: Applied in equipment handling seawater and brine where resistance to localized corrosion is critical.
▪ Pulp & Paper Industry: Utilized in bleaching systems and equipment handling aggressive chlorine-based chemicals.
▪ Oil & Gas Sector: Used in sour gas service for wellhead components and downhole equipment.
▪ Overlay & Cladding: Used for high-performance corrosion-resistant surfacing of various steels.
