Tungsten Carbide Buttons
YG8 Tungsten Carbide Button K20 K30 K40 Medium or coarse Grain size
YG8 Tungsten Carbide Button K20 K30 K40 Medium or coarse Grain size 1. Description: YG4C Mainly used as small buttons for percussion bits to cut soft and medium hard formations. Our advantage of making tungsten carbide button bits is that we are using HIP sintering for minimizing the porosity of carbide blank for increasing the transverse rupture strength (TRS). It is very suitable for high quality requirement for making carbide buttons to be used in high and medium pressure
