Non magnetic
drill collar It's made from
N***0 low carbonalloy-steel and forged by strict chemical analysis.
By testing its mechanical properties, we can ensure? the material's
hardness,toughness, impact value and corrosion resistance conform
to the standard. It has favorable low-permeability and machining
properties.Magnetic permeability
(MPS=1?**5/4?Nm) max:1.**0 Average value: ?r

non-magnetic drill collars with specifications of **5, **9, **1 and
**5, as well as some non-magnetic short drill collar with
specification of?5.5m,4.5m?and?3m. All customers (
