SMF166 is a Cr-Mn-N non-magnetic Electro Slag Remelted (ESR) stainless steel. It has been specially developed to exhibit enhanced resistance to both pitting and galvanic corrosion. It is suitable for use in critical non-magnetic drill string components including MWD tools, LWD tools, Stabilisers and Compressive Service Drill Pipe.
SMF166 has been designed to be used in place of standard Cr-Mn steels, in situations where increased corrosion resistance and 'high strength' characteristics are required.
SMF166 complies, as a minimum, to the mechanical property requirements of API 7-1. Each collar is mechanically tested. Each collar is tested for magnetic 'hotspots' using a Foerster EC Probe. Maximum deflection guaranteed less than ± 0.05μ T. Each collar is ultrasonically examined along its entire length. Certification includes all relevant physical, chemical, mechanical, magnetic and ultrasonic results.
Jiyuan Cofaith Industry Co., Ltd is a qualified manufacturer of machinery and spare parts, who has the capability in smelting, foundry, forging, heat-treating, precision machining and assembling.
