COBALTHARD 1FC

AWS Speicication:AWS A5.13/AME A5.13 ECoCr-C

Jis Specification:NONE

Other Specificvation:NONE

I. APPLICATIONS:

Hard surfacing of valve heads, seal rings of high pressure pump and parts of crushers.

II. DESCRIPTION:

COBALTHARD 1FC covered electrode is the highest hardness standard alloy in the group of cobalt alloys used for elevated temperature abrasive wear associated with corrosion. Deposits of this alloy have a large volume of chromium carbides that impact outstanding abrasive wear resistance. The addition of tungsten enhances high temperature hardness and matrix toughness for excellent adhesive and solid particle erosion wear resistance. It bonds well with all steels, including stainless.

III. NOTES ON USAGE:

Preheat at 300ºC and over in general. Use PHILARC temperature indicating sticks or PHILARC interpass temperature gauge to determine if proper temperature is achieve before welding. For more details see PHILARC Chart 4 Easy Steps for welding.
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. Use PHILARC portable drying ovens.
