Product Description
ERNiCrCoMo-1 is a high-performance nickel-chromium-cobalt-molybdenum solid welding wire compliant with AWS A5.14/A5.14M standards, specifically designed for welding INCONEL® 617 (UNS N06617) and other heat-resistant alloys.It features a robust composition with nickel as the remainder, 20.0-24.0wt.% chromium, 10.0-15.0wt.% cobalt, and 8.0-10.0wt.% molybdenum.This filler metal is compatible with GTAW (TIG) and GMAW (MIG) processes.It is an exceptional candidate for joining homogeneous alloys, dissimilar welding between various high-temperature alloys (such as INCOLOY® 800HT and cast alloys like HK-40), and for high-temperature corrosion-resistant overlay cladding。
Features
▪ Exceptional High-Temperature Strength and Oxidation Resistance: ERNiCrCoMo-1 weld metal provides an outstanding combination of high-temperature strength and oxidation resistance, maintaining its integrity at temperatures from 1500°F (815°C) up to 2100°F (1150°C).This makes it ideal for components exposed to extreme thermal cycles.
▪ Superior Metallurgical Stability: The alloy is characterized by its excellent metallurgical stability, ensuring that welded joints retain their mechanical properties and resistance to embrittlement during long-term service at elevated temperatures.
▪ Versatile Dissimilar Metal Joining: ERNiCrCoMo-1 is a preferred choice for joining a wide range of dissimilar high-temperature alloys and cast materials, providing reliable transitions in complex engineering structures.
Applications
▪ ERNiCrCoMo-1 is widely utilized in the most demanding high-temperature industrial sectors:
▪ Aerospace Industry: Used for gas turbine engine components, including combustion chambers, afterburners, and transition liners.
▪ Energy Sector: Ideal for high-temperature gas-cooled reactor (HTGR) components and critical boiler parts in power generation.
▪ Petrochemical Industry: Applied in high-temperature processing equipment, reactors, and heat exchangers where thermal stability is vital.
▪ Industrial Furnaces: Utilized in heat-treating equipment, furnace tubes, and support structures exposed to extreme heat.
