WC-20Cr3C2-7Ni termo sprej u prahu

  • Agglomerated and sintered gray-black spherical or near-spherical particles with good flowability.
  • The maximum service temperature is up to 750℃. It can be used in humid environments.
  • The dense coating has excellent resistance to oxidation, corrosion, and abrasion.
  • Anti-oxidation and corrosion resistance are better than WC-Co – based coatings.
  • Mainly used in the steel & iron industry, paper making, pump valves, etc.
