Non-magnetic drill collar!
NMDC!
Non-magnetic drill collars are made of a low-carbon, high-chromium-manganese alloy steel. They are refined through strict chemical composition ratio and forged to achieve their mechanical properties. They have good low magnetic permeability and high strength. Mechanical properties, excellent resistance to intergranular corrosion cracking and excellent wear resistance. When the magnetic field intensity is 1×105/4π A/m, the relative magnetic permeability μr of the non-magnetic drill collar is ≤ 1.010.
