ERNiCrMo-8 MIG & TIG Welding Wire

The ERNiCrMo-8 MIG & TIG Welding Wire filler wire offered by Metals And Welding Specialities is a high-performance nickel-chromium-molybdenum alloy designed for critical welding applications that demand superior corrosion resistance and mechanical strength. This alloy, also known under the UNS N06625 designation and conforming to ASTM A494 Grade CW6MC, is widely recognized for its exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking in both oxidizing and reducing environments. Its universal standard name, Nickel Alloy 625, highlights its reliability across industries where durability under extreme conditions is non-negotiable.

Manufactured with precision at Metals And Welding Specialities’ advanced facilities, the ERNiCrMo-8 welding wire ensures consistent weld quality and stable arc characteristics in both MIG (Metal Inert Gas) and TIG (Tungsten Inert Gas) processes. Its outstanding metallurgical stability makes it suitable for joining Nickel Alloy 625 and other nickel-based alloys, as well as dissimilar materials such as stainless steels and low alloy steels. This alloy is engineered to retain strength at high temperatures while offering excellent oxidation resistance up to 1000°C, making it an ideal choice for aerospace, marine, chemical processing, and power generation applications.

The ERNiCrMo-8 wire’s chemical composition features balanced levels of nickel, chromium, molybdenum, and niobium, which together deliver remarkable weld integrity and corrosion protection. Its low carbon content helps prevent carbide precipitation during welding, ensuring a clean, defect-free weld deposit. Whether used for overlaying or joining, it maintains toughness and ductility even under severe thermal cycling and mechanical stress. This makes it a preferred filler metal for welding components such as heat exchangers, turbine housings, pressure vessels, and piping systems exposed to aggressive environments like seawater or acidic media.

Industries such as automotive, foundry, repair, shipbuilding, and machinery maintenance rely on Metals And Welding Specialities’ERNiCrMo-8 filler wire for restoring worn or damaged parts. From repairing engine blocks, gear housings, and cylinder heads to resurfacing pump components, this wire ensures long-lasting, high-quality welds. It also minimizes the need for preheating and post-weld heat treatment, making it a practical choice for on-site repairs and maintenance operations.

Metals And Welding Specialities is a trusted manufacturer and supplier of premium welding consumables that meet global standards. The ERNiCrMo-8 MIG & TIG Welding Wire wire is produced under strict quality controls and tested to ensure uniform feedability, minimal spatter, and a smooth bead appearance. It complies with the highest international specifications, offering reliable performance in demanding fabrication and maintenance operations. For industries that require durability, precision, and corrosion resistance, Metals And Welding Specialities delivers a welding solution that stands the test of time.
