Non-magnetic Drill Collar

Description

?It?s made from N***0 low carbon alloy-steel, refined and forged by strict chemical analysis to reach its mechanical properties. It has favorable low-permeability, high-strength mechanical properties, great splitting properties of corrosion resistance and excellent abrasion performance.
