Eagle P-66 Tungsten Carbide Spray Powder | High-Heat Hardfacing Alloy

Eagle P-66 is recommended for:

Mixer paddles
Pug mill knives
Augers
Cultivator shovels
Ash chutes
Chains
Hog hammers
Guide nozzles
Plungers
Valves
Debarker knives
Steel components
Nickel-alloy components
Cast iron
High-heat wear applications
Edge build-up applications

Designed for applications where severe abrasion, elevated heat and edge retention are important.

Clean the surface thoroughly and remove oil, grease and scale.

Use a grinder to remove oxides where required.
Preheat the base metal to approximately 400°F.

Use a 1–1½" slightly carburizing flame and pre-spray the area to approximately 0.005" thickness.

Release the feed lever and heat until a sweating action occurs.

Weave the torch and add Eagle P-66 powder until the required dimension is achieved.

Allow the component to cool slowly.

Eagle P-66 is a tungsten carbide spray powder in a tough nickel-base matrix designed for hardfacing steels, nickel alloys and cast iron.

The alloy produces a very hard wear-resistant deposit and is specifically noted for resisting the softening effects of high heat and providing excellent edge build-up.

Why Eagle P-66?

High hardness — approximately 60–64 HRC.
Tungsten carbide wear resistance — designed for severe abrasive service.

High-heat performance — resists softening when exposed to elevated temperatures.

Excellent edge build-up — useful on knives, edges and similar wear surfaces.

Broad base-metal compatibility — suitable for steels, nickel alloys and cast iron.

P-66 or P-22?

This comparison is useful because they are both tungsten-carbide powders at approximately 60–64 HRC.

P-22 = tungsten carbide severe-abrasion powder
P-66 = tungsten carbide severe-abrasion powder with published emphasis on high-heat resistance and excellent edge build-up

So the clean positioning is:
P-22 = severe abrasion
P-66 = severe abrasion + high heat + edge build-up

Preheat Temperature: Approx. 400°F
Flame: Slightly Carburizing
Initial Pre-Spray Thickness: Approx. 0.005"
Cooling: Cool Slowly
Finishing: Grind using a hard silicon carbide wheel
