Chromium Carbide Powder

We produce and stock customizable chromium carbide (Cr3C2, Cr7C3, Cr23C6) powders providing extreme hardness, low coefficient of friction surface finish, high wear resistance, and excellent oxidation/corrosion resistance.

Chemical Formula

Cr3C2, Cr7C3, Cr23C6

Synonyms

Chromium carbide, chromic carbide, methanidylidynechromium

Applications

  • Corrosion resistant structural parts and coatings. Parts and coatings requiring oxidation and corrosion resistance such as valve seats, valve orifices, bearings, and seals.
  • Wear surface (wear resistant) parts and coatings. Parts and coatings that undergo fretting, abrasion, cavitation, and particle erosion such as cyclones,  fan blades, turbine blades, liners, chutes, hoppers and feeders.
  • Welding Rod/Wire Filler. Iron-based wires coated with chromium carbide in an iron-based matrix material to produce extremely  wear resistant deposits using the oxy-acetylene welding process.
  • Additives. Our chromium carbide powder is added to other sintered carbides to inhibit grain growth during pressing and sintering.
