Non-magnetic steel is a type of steel that does not have magnetic properties. It is used in the oil and gas industry for various applications that require a non-magnetic material. For example, non-magnetic steel is used for drilling and logging operations, as it does not interfere with the magnetic sensors and measurements. Non-magnetic steel is also used for reactor nozzles, bed supports, catalyst screens, thermowells, and gasketing in the oil and gas industry. Non-magnetic steel is usually made of austenitic stainless steel, which has a high chromium and nickel content that prevents the formation of magnetic domains in the metal's structure. Non-magnetic steel has high strength, corrosion resistance, and durability, making it suitable for harsh environments.
