ABSTRACT:
A hard surfacing alloy which has a Rockwell C hardness of greater than about 50 and which includes tungsten carbide, chromium carbide and bi-metallic chromium and tungsten carbide crystals which are precipitated in the alloy. Alloys of the present invention in their nominal composition comprise from about 12% to about 20% tungsten; from about 13% to about 30% chromium; an effective amount of carbon for forming carbides with the tungsten and chromium and include effective amounts of fluxes and melting point depressants and the like. The balance of the composition is nickel. The alloys include precipitated carbide crystals of chromium, tungsten and bi-metallic mixtures thereof which are interspersed through the hard surfacing alloy and are metallurgically bonded in the metal matrix of the alloy. The alloys have extremely low porosities and therefore are suitable for glass plunger and other applications where low porosity is essential.
