NIDURIT 63

Specification
AWS Specification: AWS A5.13 EFeCr-A1
JIS Specification: 
Other Specification: N/A
Description
  • NIDURIT 63 is a chromium carbide electrode for hardfacing applications
  • Features excellent properties due to spray arc and easy slag removal
  • Perfect for rejuvenating worn parts and putting them back to service condition
  • In the sugar industry, NIDURIT 63 increases the service life of equipment and results in continuous production and reduction of downtime during crushing season
  • Approx. Recovery: 170%

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.

  • Suited for parts subject to mineral friction wear combined with light impact, such as mixer, wings, conveyor screws, scraper blades, and digging teeth
  • Commonly used in sugar production industries
  • Hold electrode as vertically as possible
  • Keep a short arc
  • Reduce dilution with the base metal by weaving
  • For multi-pass applications, a cushion layer with NSS-307 is recommended
  • Re-dry electros that have gotten damp at 200ºC for 2 hours
