Applications of Stellite Alloy (Cobalt Chrome ALloy)

  • Applications of Stellite Alloy (Shenyang Top New Material Co.,Ltd Manufacture).

    It include saw teeth, hardfacing, and acid-resistant machine parts. Stellite was a major improvement in the production of poppet valves and valve seats for the valves, particularly exhaust valves, of internal combustion engines. By reducing their erosion from hot gases, the interval between maintenance and re-grinding of their seats was dramatically lengthened.

    Stellite 3 has also been used in the manufacture of turning tools for lathes. With the introduction and improvements in tipped tools it is not used as often, but it was found to have superior cutting properties compared to the early carbon steel tools and even some high speed steel tools, especially against difficult materials such as stainless steel. Care was needed in grinding the blanks and these were marked at one end to show the correct orientation, without which the cutting edge could chip prematurely.

    The perpetual demand for oil and gas pushes companies to optimize the extraction process to be as efficient as possible. Various components of drilling hammers used in oil extraction experience abrasion from mud, metal-to-metal wear and erosion. To combat excessive wear, drilling hammers are hardfaced with composite alloys of tungsten carbide, dispersed in a nickel or cobalt-based matrix. Plasma transferred arc (PTA)deposits of Ni-Cr-B-Si alloys are used to combat wear on plungers, sleeves, sucker rods and seals of mud pumps and submersible pumps.

    In the refining sector, cobalt-based alloys applied by PTA are used extensively to combat wear, erosion, abrasion and corrosion.
