Nonmagnetic steel refers to any type of steel that is not attracted to a magnet. Synonyms for nonmagnetic steel include austenitic stainless steel, nickel alloy, 300 series stainless steel, and nonferrous alloys. These types of steel are typically used in applications where magnetic properties are undesirable, such as in medical equipment or electronics. Additionally, nonmagnetic steel is often used in environments where magnetic interference can cause problems, such as in aircraft or nuclear power plants. Regardless of the specific alloy, nonmagnetic steel offers a wide range of unique properties and uses, making it an important type of steel in many industries.
