Non-magnetic drill collars

 

Non-magnetic drill collar adopts a kind of chrome manganese alloy steel as material, low carbon obtained by combining a proprietary chemical analysis and rotary hammer process. The material is resistant to corrosion crack, with low magnetic conductivity, with no tendency to galling and high wearproof performances. 
Magnetic permeability (when MPS=1105/4NM) relative maxπμr :1.010.
Magnetic field gradient (hot spots) max.: B 0.05micro tesla/100mm
