Hardfacing Materials
Non-magnetic Hardfacing Materials
DURUM’s commitment to investing in new technological
advances, as they relate to material science and process
application has resulted in several recent developments that
have demonstrated superior performance in terms of reducing
wear on critical downhole tools while improving consistency in
harsh/aggressive drilling environments.
Primarily, non-magnetic drill collars are used to reduce the
interference of the magnetic fields that may affect dedicated
directional equipment. In respect, DURUM has focused their
efforts towards developing new materials for the hardfacing of
non-magnetic drill collars and stabilizers with the specific intent
of minimizing magnetic survey errors.
Our materials meet the magnetic (relative) permeability
requirements of API specification 7 and have achieved results
below the magnetic field gradient (hot spot) of 0.05 micro
Tesla/100 mm.
Materials for non-magnetic hardfacing include:
