I. APPLICATIONS:

N-NiCrMo-2 is commonly used in the chemical process industry for retorts, muffles, catalyst support grids, furnace baffles.  It is also used for engine tailpipes, turbine blades, afterburner components, nozzles vanes, cabin heaters and other aircraft related parts. 

     II. DESCRIPTION:

N-NiCrMo-2 is a nickel-chromium-molybdenum electrode developed for shielded metal-arc welding of similar base metals such as Hastelloyl® X to themselves or to stainless steels and low alloy steels. NIHONWELD N-NiCrMo-2 offers an exceptional combination of oxidation, corrosion and thermal shock resistance.  This electrode exhibits high temperature strength and prevents weld metal fatigue at temperature as high as 2200ºF 

III. NOTES ON USAGE:

  • Its weldability is as same as austenitic stainless steels.

  • Keep the interlayer temperature under 100ºC and cool it as fast as possible.

  • Keep the welding current as low as possible.

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

TEST RESULT

The information contained or otherwise referenced herein is presented only as “typical” without guarantee or warranty, and Industrial Welding Corporation expressly disclaims any liability incurred from any reliance thereon. 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.
