DEFINITION

Classification: 75/240

Carbide only of Chromium (Cr), Molybdenum (Mo), or Tungsten (W):

(under subclass 236) Subject matter restricted to the carbides of chromium, molybdenum and/or tungsten.

SEE OR SEARCH THIS CLASS, SUBCLASS:

236, for a similar composition in which the carbide of a metal other than Chromium (Cr), Molybdenum (Mo), or Tungsten (W) may be used alternatively to the carbide of Chromium (Cr), Molybdenum (Mo), or Tungsten (W).

241, for a composition in which Chromium (Cr), Molybdenum (Mo), or Tungsten (W) carbide is used in addition to the

carbide of a metal other than Chromium (Cr), Molybdenum (Mo), or Tungsten (W).
