14700: P Z Co2
Applications

CEWELD Powder PTA DUR 6 is a cobalt-base metallic powder with spherical shape and is designed for plasma-transferred-arc (PTA) welding process.  

It is especially suited for hardsurfacing of parts subject to a combination of erosion, corrosion, cavitation, pressure, impact and abrasion and high temperatures up to 900 °C, such as tight surface of fittings, valve seats and cones for combustion engines, gliding surfaces metal to metal, highly-stressed hot working tools without thermal shock, milling, mixing and drilling tools

Properties

CEWELD Powder PTA DUR 6 deposit can be machined  with tungsten tool tips and by grinding.

The hardness of the deposit will degrease 16% at 300°C and about 30% at 500°C form approx. 45 HRC in the second layer welded by PTA process. CEWELD Powder PTA DUR 6 is a excellent alloy against thermal shock, abrasion, erosion, corrosion and cavitation at high temperature and excellent resistance to many forms of mechanical and chemical degradation over a wide temperature range, and retains a reasonable level of hardness up to 500°C (930°F).

Melting temperature:  1285 – 1410 °C

Density: 8.44 g/cm3
