ENiCrMo-3 is a high-performance nickel-chromium-molybdenum alloy welding wire designed for welding Inconel® 625 and similar high-temperature, high-stress materials. Known for its exceptional resistance to oxidation, thermal fatigue, and corrosion, ENiCrMo-3 is suitable for welding applications in extreme environments where reliability and performance are critical.
This alloy is widely used in petrochemical, power generation, aerospace, and heat-treatment equipment manufacturing, especially in applications subjected to high temperatures and aggressive environments.
