COBASTEL 1

• Rutile-basic electrode with alloyed core wire, for welding with alternating current.
• A cobalt-based overlay with an austenitic-ledeburic structure with embedded tungsten carbides (CrW).
• The hardest of the standard cobalt-based alloys.
• The overlay is resistant to corrosion, impact, abrasion, as well as thermal shocks and high mechanical pressure.
• The overlay is workable only by grinding.
• Operating temperature: from room temperature to 1000°C.

Recommendations:

• The operating temperature should be maintained between 400° and 600°C, depending on the base material and type of construction.
• Slow cooling, and if required furnace cooling, is recommended for low alloy and austenitic steels.
