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.

  • Steel rail ends
  • Dredge buckets
  • Heavy crushing equipment
  • Jaw crusher
  • Swing hammer
  • Tooth crusher rolls
  • Ore crusher crown wheels
  • Avoid continuous welding
  • Recommend to water cool during welding
  • It is necessary to underlay with austenitic stainless steel in such case when the base metal is not 13% manganese steel
  • When the base metal of 13% manganese steel is hardened, remove it before welding
  • Dry the electrodes at 150 - 200ºC for 30 - 60 minutes before use
