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.

  • Preheat at 300C and over in general
  • Effective to postheat at 600C and to slow cool after welding to prevent cracking
  • Dry the electrodes at 150-200C for 30-60 minutes before use
  • Hardsurfacing of parts subject to heavy abrasion with moderate impact
  • Sinter breaker plants
  • Scraping beaks in zinc industry
  • Blast furnace charging equipment
  • Vegetable oil press screws for palm or cocounut
