Moly hardness
WebThese alloys exhibited a lower hardness as compared to the tungsten/ molybdenum carbide-based alloys patented by Lohmann and Voigtländer ... Molybdenum carbide will hardly be stable in a plug flow reactor [26], because the carbide will be oxidized at the inlet. 4.2.5.3 Non-Catalytic Reforming. Non-catalytic steam reforming requires high ... WebTherefore, we cannot say that either chromium-molybdenum or chromium-vanadium is better. Either Cr-Mo or Cr-V is an excellent choice for all normal uses of wrenches, hand-driven sockets, impact sockets, ratchets, and other similar tools. The metallurgical difference between Cr-Mo and Cr-V is insignificant in these applications.
