Non-magnetic Drill collars are made from Non-magnetic drill collar materials with low- strength (SWNM20-14) by combining a proprietary chemical analysis and a rotary hammer forging process with low magnetic permeability excellent machine ability. The material is resistant to stress corrosion cracking, with high machine ability and no tendency to galling.
Each drill collar is fully inspected by internal inspection dept. Strict to control of chemical composition and special forging process guarantee the excellent mechanical properties of SENWELL’S non-magnetic tools.
