 Non-Magnetic drill tools

Materials of TianHe Non-magnetic drill collars are made from chrome manganese low carbon austenitic alloy, which has following characteristic:

The chemical composition should be controlled strictly during the refining and forging process.

With excellent lower Magnetic permeability, high strength of mechanical properties and outstanding resistant to stress corrosion cracking and no tendency to galling.
