About Stellite-Type Cobalt Alloy Powder [-325+400]

Stellite-type alloys are cobalt-based materials strengthened primarily by chromium and tungsten carbides. In powder form, they are widely used to apply hard, oxidation-resistant overlays on components that operate in harsh environments. The -325+400 mesh cut (approximately 38–44 µm) is a common choice for high-velocity oxy-fuel (HVOF) spraying, where a fine, narrow particle range helps produce coatings with low porosity and high bond strength.

This powder is also suitable for plasma and flame spray setups, depending on the specific equipment and application parameters. The resulting coatings typically exhibit a balance of hardness and toughness, making them effective on pump sleeves, valve seats, bearing journals, and other parts subject to metal-to-metal wear or cavitation.

Key Selection Considerations

  • Particle size: The -325+400 mesh range is optimized for HVOF guns that require a fine, free-flowing powder. Confirm compatibility with your feed system before ordering.
  • Chemistry: Cobalt-chromium-tungsten compositions vary by manufacturer. Request a detailed chemistry certificate to match your coating specification.
  • Pack sizes: Standard options include 5 kg tins, 10 kg tins, and 25 kg pails. Bulk packaging may be arranged on request.
  • Process fit: While HVOF is the primary target, this cut can be evaluated for plasma and flame spray. Discuss your process parameters with our team to confirm suitability.

General Hardfacing

Use on components requiring a dense, low-porosity overlay resistant to metal-to-metal wear.

FAQ

Which mesh size should I choose?
Mesh depends on your spray process and coating requirement. Use the mesh table on the product page, or select Custom and describe your need.
Which spray processes are supported?
Typical processes include HVOF, plasma spray, flame spray and cold spray. Select your process in the quote form so we quote the right grade.
Can I order a sample or bulk powder?
Yes. Ask for a sample bottle or bulk drums. Enter quantity and choose Kg, Bottle or Drum in the form.
Can you share a certificate or material data sheet?
Yes. Request a COA or datasheet in your enquiry and we share available documents with the quote.
