Abstract: This application relates to lightweight steels, preparation methods thereof, and steel structural parts and electronic devices that use the lightweight steel. An example light weight steal includes: Fe, in a percentage by weight greater than or equal to 48.18 wt %; Mn, in a percentage by weight of 30.01 wt % to 35.01 wt %; Al, in a percentage by weight of 12.01 wt % to 15.01 wt %; C, in a percentage by weight of 1.0 wt % to 1.5 wt %; and O, in a percentage by weight of 0.03 wt % to 0.3 wt %. This application further provides a steel structural part, an electronic device that use the lightweight steel, and a preparation method of the lightweight steel.
