Description
  • NSS-307 is a lime-titania stainless steel electrode that forms the deposited metal of 9%-19% Ni - 5% Mn stainless steel with the perfect austenitic structure
  • Deposited metal has excellent crack resistibility and shows easy work hardening

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.

  • Welding of 14% Mn steel, steel armour, hardenable steel, and generally all hard-to-weld steels
  • Joining of wear plates to each other
  • Joining of stainless steels to carbon steels
  • Building up of rails and buttering layers before hardfacing on 14%Mn steel, steels of unknown composition, or on carbon steels
  • Extensively used in steelmaking public works, mining, carrying, and dredging
  • Remove dirt, such as oil and dust from the groove
  • Keep the welding current as low as possible
  • Keep the arc length as short as possible
  • Re-bake the electrode at 200-250ºC for about one hour before use
