ER NiCrMo-3
ER NiCrMo-3 (also written ernicrmo3) is a premium nickel-based welding wire with excellent corrosion resistance, strength and toughness. It is well suited to MIG and TIG welding of nickel-chromium-molybdenum alloys such as Inconel 625, producing durable, stress-free welds with consistent results in chemical, marine and oil & gas service.
Product details
Main Features and Benefits
ER NiCrMo-3 is built for high-performance welding, combining strength, durability and reliability in demanding industrial use.
- Outstanding corrosion resistance in harsh media, including acids, alkalis and seawater, so it suits chemical, petrochemical and marine work.
- High tensile and yield strength that keeps components structurally sound under heavy loads and dynamic stresses.
- Excellent toughness and ductility, which lower the risk of cracking during welding and cooling cycles.
- Flexible process compatibility: it runs on both MIG and TIG, giving freedom across many fabrication and repair tasks.
- Dependable across a wide temperature range, from cryogenic conditions up to approximately 540°C (1000°F).
- Uniform weld quality that supports long-term durability and a dependable service life in demanding industrial settings.
- Less post-weld repair thanks to improved crack resistance, saving time, cost and fabrication effort.

These properties explain why ER NiCrMo-3 is chosen for such a broad range of industrial welding projects:
- Superior corrosion resistance in harsh environments – ER NiCrMo-3 stands up very well to acids, alkalis and seawater, which makes it a good choice for demanding applications where material life and reliability are critical.
- Holds its strength at high and low temperatures – the filler wire keeps its mechanical strength under extreme conditions, from hot operations to cryogenic service, so performance and structural integrity stay consistent over a wide temperature range.
- Exceptional toughness and ductility – the toughness allows welds to absorb stress and vibration without failing, and the ductility gives flexibility in fabrication while reducing the chance of brittle fracture.
- Excellent crack resistance – the alloy formulation lowers the risk of cracking during welding and cooling, giving durable, safe and long-lasting welds that satisfy strict industrial standards.
- Easy to handle and weld – designed for operator convenience, ER NiCrMo-3 welds smoothly with minimal spatter, so fabricators can shorten production time, cut costs and get high-quality results easily.
Taken together, these properties make ER NiCrMo-3 a dependable and efficient answer for industries needing durable, high-performance welds under challenging conditions.
