In the energy industry, stainless steel is mainly used in the oil, natural gas and chemical industries in terms of transportation pipelines, storage tanks and other fittings. Because of its excellent corrosion resistance and ability to maintain surface finish and chemical properties for a long time, stainless steel is widely used in energy fields such as oil and gas extraction, petrochemical and chemical industries. In addition, stainless steel can also be used in the field of nuclear energy, such as instruments, equipment and piping. As the nuclear reaction will produce intense radiation, and stainless steel has good radiation resistance, can effectively resist the destruction of strong radiation on the equipment, thus ensuring the safety of the nuclear energy field.
