Product Description
ERNiCrMo-4 Welding Wire (Inconel 686 / UNS N06686 / Nickel Alloy)
High-performance corrosion-resistant filler metal for critical applications
Product Overview
ERNiCrMo-4 is a premium nickel-chromium-molybdenum-tungsten (NiCrMoW) alloy welding wire designed for the most demanding corrosion environments. Equivalent to Inconel 686 (UNS N06686), this wire delivers exceptional resistance to a wide range of corrosive media including strong oxidizers, acids (sulfuric, hydrochloric, nitric), seawater, and high-temperature gases.
Ideal for both cladding and joining, ERNiCrMo-4 is widely used in chemical processing, flue gas desulfurization (FGD) systems, marine engineering, and pollution control equipment. Compatible with TIG (GTAW) and MIG (GMAW) welding processes, it provides crack-free, durable welds with excellent mechanical and corrosion-resistant performance.

Key Features
- Outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking
- Performs in aggressive oxidizing and reducing environments including wet chlorine, hot acids, and seawater
- High-temperature strength and structural stability up to 1000°C
- Excellent weldability and arc stability in both MIG and TIG processes
- Suitable for overlay welding on carbon or stainless steel components
- Conforms to AWS A5.14 ERNiCrMo-4 / UNS N06686
Common Names / Designations
- AWS: ERNiCrMo-4
- UNS: N06686
- Equivalent: Inconel 686, Alloy 686, NiCrMoW
- Other Names: Alloy 686 welding wire, high-performance nickel alloy filler, corrosion-resistant overlay wire
Typical Applications
- Chemical reactors and pressure vessels
- Flue gas desulfurization (FGD) systems
- Seawater piping, pumps, and valves
- Marine exhaust and pollution control equipment
- Dissimilar metal welding and protective cladding
- Heat exchangers in aggressive chemical media
