CEWELD PTA DUR 21 powder is particularly suitable for hardfacing of parts exposed to a combination of corrosion, impact and abrasion, high temperatures up to 900°C, oxidation in corrosive environments at high temperatures.
The powder has excellent sliding properties, good polishability, high toughness, non-magnetic. Can be machined with cutting tools.
At 20 °C: approx. 35 HRC in the second layer welded by PTA process
At 600 °C: approx. 280 HB in the second layer welded by PTA process
CEWELD Powder PTA DUR 21 is designed for plasma-transferred-arc (PTA) welding processes as well as for laser cladding.
