API 11AX titanium carbide valve balls and tungsten carbide valve seats
It is used for places requiring extreme hardness and resistance towear and abrasive, hard shocks and impacts. They can be used for special valves, flow meters, recirculating balls bearing screws, liner bearing and balls for ball point pens. They are also used for mining, as pivols and points of comparations. What's more, they are also used for measurements or colibrations of holes and measurement checking devices.
