Product overview
The YD tungsten carbide composite rod is made of superior cemented carbide grits in Nickel Silver or Brass Bronze.
With perfect properties of high hardness, excellent corrosion, abrasion resistance, high pressure and temperature resistance.
It’s designed to form soldering hard-facing on fishing tools used during fishing jobs in oil, gas and exploratory well bores. Mill surfacing and renewal is carried out both in workshops and oilfield.
