NOTE:

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.

  • Used for welding on C-4, NiMo16Cr16Ti, and surface cladding on low alloyed steels
  • Weldability is the same as austenitic stainless steel
  • Keep the interlayer temperature under 100C and cool it as fast as possible
  • Keep the welding current as low as possible
  • Dry the electrodes at 150-200C for 30-60 minutes before use
