I. APPLICATIONS:

Since N-NiCrFe-3 is so versatile, it can be used for countless applications.

However more common applications include the chemical or petrochemical industries and the nuclear industry where it is used to weld dissimilar joints between vessels and primary piping. NIHONWELD N-NiCrFe-3 is often used for welding the clad side of nickel-chromium-iron clad steel and for re-surfacing steel.

      II. DESCRIPTION:

N-NiCrFe-3 is a “General Purpose” nickel-chromium-iron flux-coated electrode used for joining many dissimilar combinations of nickel base alloys, of the nickel chromium type, to themselves or to stainless or mild steels. This electrode will consistently produce x-ray quality and machinable weld deposits. Excellent for welding Inconel® 600 to itself or to carbon steel and stainless steels; or high chromium Incoloy® 800 to nickel-copper Monel® 400 or nickel base alloy 200. NIHONWELD N-NiCrFe-3 is also used for joining nickel base alloy 200 to stainless steel and nickel-copper Monel® 400 to carbon steel

     III. NOTES ON USAGE:

  • Preheating is not necessary in general.

  • Avoid the continuous welding if possible. It is effective to weld under 150ºC for reducing cracking tendency.

  • Dry the electrodes at 150 ~ 200ºC for 30 ~ 60 minutes before use.

Typical data and Test results for mechanical properties, deposit or electrode composition and other properties were obtained from a weld produced and tested according to prescribed standards, and should not be assumed to be the expected results in a particular application or weldment. Actual results will vary depending on many factors, including, but not limited to, weld procedure, plate chemistry and temperature, weldment design and fabrication methods. Users are cautioned to confirm by qualification testing, or other appropriate means, the suitability of any welding consumable and procedure before use in the intended application.
