Exaton NiCrMo-3

Exaton NiCrMo-3

NiCrMo-3 welding wire is suitable for joining nickel-chromium-molybdenum nickel alloys and chromiumnickel-molybdenum steels with very high corrosion resistance in oxidizing, aqueous and high temperature environments such as 6Mo-steels, UNS N06625 (2.4856) and corresponding grades. It is also suitable for joining stainless steels and nickel alloys for high-temperature service. NiCrMo-3 can also be used for dissimilar joining of stainless steels to nickel alloys, for overlay welding and it is used for MIG/MAG welding. Applications for NiCrMo-3 are found in cryogenics, components subject to high temperature service up to 980°C (1800°F) such as aircraft ducting, engine exhaust systems, power boilers and recovery boilers and a diversity of seawater applications. The combination of strength and corrosion resistance over a wide range of temperatures is utilized in reaction vessels, line pipe distillation columns and heat exchangers.

Where To Buy Request Information

For SAW Stainless Steel Welding in Heavy Duty Environments

Developed from a legacy of over 80 years in specialty alloy filler metals, Exaton (formerly Sandvik Welding Operations) is the leading brand in high-quality, corrosion-resistant filler metals. Products are made for welding stainless steel and nickel alloys in the most demanding environments.

Unbeatable Quality in SAW Wire

Wire quality is consistent from batch to batch in terms of chemistry, mechanical properties and dimensional tolerances. Get consistent welds with no need to trim the parameters.

Innovative Corrosion-Resistant Chemistry

Exaton's innovative chemistry provides high corrosion resistance with increased content of chemical elements such as Cr and Mo. It also delivers productivity improvements, such as permissible finished chemistry with a single layer weld overlay in applications that traditionally required two or even three layers.

SAW Flux with Less Moisture & Damage

Steel drum packaging delivers high moisture resistance and less damage during shipping and handling. This better protects the flux inside. Available in 20-25 kg drums.

SAW Flux that Helps You Save

Electroslag welding is similar to submerged arc strip cladding. The difference, however, is in the flux. ESW flux provides increased speed and fewer cladding layers (weld deposit), resulting in an overall lower cost of operation. Savings are in consumable costs and fewer man hours required.
