Product catalog summary

Description: Eutroloy 6606PG is a nickel-chromium-molybdenum alloy powder designed for the plasma transferred arc process. It produces hard, dense, and pore-free coatings that are alloyed with the base metal, offering excellent weldability and performance in various corrosion environments. The coatings are suitable for applications requiring resistance to low stress abrasion and corrosion, with grinding using coarse grit silicon carbide wheels recommended for finishing.

Typical Applications: The alloy is used in waste incineration, chemical processing, recovery boilers, and fly ash fans.

Powder Properties: The chemical composition includes Boron (3%), Silicon (4.4%), Chromium (17.5%), Iron (3.5%), Nickel (balance), Carbon (0.3%), Molybdenum (12.0%), and Copper (2.0%).

Procedure for Use: Damaged material should be removed, and areas to be welded cleaned. Heat input should match the component's material and dimensions, with low dilution with the base metal. Allow the workpiece to cool slowly after welding.

Coating Properties: The macro hardness is HRC 55, micro hardness HV 550, coating density 8.1 g/cc, maximum service temperature 1922°F (1050°C), G65 volume loss 25mm3, non-magnetic response, and expansion coefficient 12.2 x 10-6.

Particle Size: US Mesh +80 (+180 um) 5% max, -270 (-53 um) 5% max.

Parameters: The plasma transferred arc system uses GAP 2001 and 3001 systems with an E52 torch. Anode and cathode specifications depend on part geometry. Shielding gas nozzle options include standard or high deposit, with argon as the pilot gas and argon/5% hydrogen as the shielding gas. The powder feeder is EP2, with powder wheel speed and feed rate dictated by part geometry. Amperage and voltage should be kept low to maintain WC integrity while ensuring a well-bonded overlay.

TYPICAL APPLICATIONS: Eutroloy 6606PG is a nickel-chromium-molybdenum alloy powder designed for the plasma transferred arc process. The coating deposits produced are hard, dense, essentially pore free and are alloyed with the base metal. The levels of alloying elements in the powder are synergistically balanced to insure good weldability along with excellent performance over a broad range of corrosion environments. Applications for 6606PG coatings include those that require a unique combination of resistance to low stress abrasion and corrosion. The recommended method of finishing is by grinding...
