Metallized Carbon Corporation Increases Range of Grade M-312 Nickel Chrome Impregnated, Carbon Graphite Material for Power Plant Boiler Feed Pump Bearings

Metallized Carbon Corporation, a global leader in the manufacture of oil-free, self-lubricating, carbon-graphite materials for severe service lubrication applications, announces the availability of the Grade M-312 nickel chrome impregnated, carbon graphite material. This material is ideal for use in sleeve bearings for power plant boiler feed pumps, where the extreme conditions require high corrosion resistance.

Power plant boiler feed pumps are large, multi-stage centrifugal pumps which supply condensate water to power plant boilers. Operating at speeds of up to 6000rpm, they supply up to 5000 gallons of hot condensate water per minute and reach pressures as high as 2900 psi. In addition, the condensate water itself can be as hot as 700° F (371° C). Sleeve bearings are continuously submerged in, and lubricated by, this hot water in these harsh conditions.

Nickel chrome impregnated, carbon-graphite is the only material that has the outstanding lubricating qualities required to run with low wear under these conditions. Since it is a homogeneous material, it will provide these same lubricating qualities throughout its entire service life. It also has the excellent chemical corrosion resistance required to withstand the long term corrosive effects of hot, condensate water.

Grade M-312 nickel chrome impregnated, carbon graphite material is also used in nuclear power plants. Since it does not contain any heavy metals, it remains dimensionally stable and does not become any more radioactive than stainless steel when irradiated with high flux neutron radiation.

Metcar's quality Management system is certified to ISO9001-2008 and all materials are manufactured to exacting standards.  Numerous quality checks are performed during the manufacturing of the material to insure the highest level of performance for each application.  The latest electronic and optical methods are used to ensure the dimensional integrity of each part.  All measuring equipment is calibrated to NIST traceable standards.
