Wear plates
CeraMetal Wear Plate is a bi-metallic plate, consisting of a mild steel base with a highly alloyed wear resistant cladding. It is produced by a customized automatic hardfacing process which results in a harder, tougher and more wear resistant surface than any existing process can achieve, as proven by abrasion tests to ASTM G65 and erosion tests to DIN 50332. (Result available on request) The low carbon steel base plate allows the product to be welded, bolted or studded to existing structures, whilst the surface cladding provides an excellent wear resistance barrier to the most severe conditions and environments. The superiority of CeraMetal Wear Plate is the direct result of strict scientific and metallurgical control of all the production processes involved. The highest available concentration of Chrome Carbides (Cr7C3 - Hardness 1730 VPN) together with the optimum Carbide orientation and the unique alloy additions makes CeraMetal Wear Plate superior to any plates of this kind available in the market.
  • Easy fabrication of components e.g. pipes, ducts, transitions e.t.c.
  • Easy welding to steel structures.
  • Easy cutting to required shape.
  • Excellent abrasion resistance of the hardface According to ASTM G65, the hardface outlasts mildsteel by 20 to 30 times. (In some cement-clinker applications by 60)
  • Good metal to metal wear resistance.
  • Good corrosion resistance due to high Chrome content.
  • Good heat resistance.
  • Very small Heat Affected Zone
  • Very low dilution of the mild steel base plate.
  • Very high Carbide concentration ( >50% in HCCr type, according to Maratray)
  • Tough austenitic matrix supporting the hard Carbides.
  • Hardness and composition designed to suit the application.

Wear Plates Fabrication Methods
  • Plasma cutting is recommended. Arc gouging can be used.
  • Forming can be performed satisfactorily as with mild steel. Generally hardface must be inside.
  • Welding mild steel base to steels is performed by using standard methods without preheating or other special measures. Standard E7018 electrodes can be used for this purpose, provided that the weldment does not interfere with the hardface. Joints on the hardface, can be covered by CeraMetal Tubular Electrodes or Hardfacing Wires.
