Nonmagnetic Drill Collar NMDC

Non-magnetic drill collar is the use of a low carbon high

chromium manganese alloy steel, it is after strict ratio of

the chemical composition of refined and achieved through

forging and its mechanical properties, good mechanical

properties of low permeability, high strength, excellent

intergranular corrosion cracking resistance and excellent

wear resistance.

When the magnetic field strength 1 x 105/4

PI for A/m, non-magnetic drill collar relative magnetic

permeability of u r 1.010 or less.
