NHF-ST6

Specification
AWS Specification: AWS A5.13 ECoCr-A
JIS Specification: DCoCr-A
Other Specification: N/A
Description
  • NHF-ST6 produces a medium hardness cobalt-chromium deposit for high temperature applications with good abrasive wear and impact resistance
  • Versatile and widely used cobalt alloy
  • Offers excellent resistance to many forms of chemcial and mechanical degradation, including galling and cavitation erosion, due to chromium carbides deposit
  • Bonds well with all weldable steels, including stainless

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.

  • Valve seats
  • Forging dies
  • Crushers
  • Hammer
  • Edges
  • Cutting knives and blowers
  • Preheat at 300ºC and over
  • It is effective to postheat at 600ºC and to slow cool after welding to prevent cracking
  • Dry the electrodes at 150-200ºC for 30 ? 60 minutes before use
