company news about MTH Carburized Threaded Drill Rod

MTH threaded drill rods are produced by carburizing technology.

Through high-temperature heating, carbon atoms are diffused to the surface of drill rod to achieve the purpose of increasing the carbon content on the surface of the drill rod .

This technology harden the entire rod surface both internally and externally, maintains basically unchanged toughness and ductility. Greatly extend the service life and promote the abrasive resistance. Not only decreased drilling cost, also increased work efficiency
