Steel components
Nickel alloys
Cast iron
Build-up before hardfacing

Designed for applications where worn material needs to be restored before final machining or hardfacing.

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

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

Use a 1–1½" slightly carburizing flame and pre-spray the area to approximately 0.004" thickness.

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

Weave the torch and add Eagle P-33 powder until the required dimension is achieved.

Allow the component to cool slowly.

Eagle P-33 is a tough nickel-base spray powder designed for fully machinable build-up on steels, nickel alloys and cast iron.

Its relatively low hardness allows worn components to be restored and subsequently machined back to their required dimensions.

Why Eagle P-33?

Fully machinable — ideal for restoring components that need post-spray machining.

Excellent build-up alloy — useful for replacing worn material and restoring dimensions.

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

Hardfacing underlay — can be used as a softer foundation beneath harder wear-resistant overlays.

P-33 or P-22?

This comparison is worth adding because they serve almost opposite purposes.

Choose Eagle P-33 when you need to rebuild worn material and machine it back to size, or when you need an underlay before hardfacing.

Choose Eagle P-22 when you need a hard tungsten-carbide surface for severe abrasive wear.

In simple terms:
P-33 = machinable build-up / underlay
P-22 = severe-abrasion wear protection
