|Part Number EnDOtec DO-04|
An exclusive, small-diameter special alloy, EnDOtec DO*04 offers E+C TEROCOTE protective coatings of high hardness (~50 HRC in one pass) ideal for machine parts subject to metal/metal friction cavitation, corrosion and oxidation at high temperatures.
Features: Excellent corrosion and oxidation resistance at temperatures up to 650Â°C, excellent metal/metal friction resistance at high temperatures, ideal for use as cladding with no risk of cracking (hardness ~50 HRC); tough, creep resistant deposit; good corrosion resistance in high temperature gaseous media: combustion chamber, diesel engine, valves, etc.; no buttering layer necessary when coating heatresistant steels of CrMo/CrMoV type; good corrosion resistance in saline environment, with cavitation resistance.
