Material characteristics: Chemical elements such as C, Mn, Si are usually used for strengthening, with little or no use of microalloying elements such as Nb, V, Ti. After the parts are made, they are mainly connected by bolt connection, riveting, and welding. The processing methods are usually bending, simple forming, and welding.

Typical applications: Widely used for general structural and stamping parts in the automotive, home appliance, and construction hardware industries. For example, automotive beam reinforcement plates, beam cover plates, supports, white goods interior panels, electrical cabinet internal structural plates, hardware guide rails, furniture door panels, office countertops, elevator box interior panels, building decoration partitions, stationery boxes, locker partitions, toolbox trays, bicycle partitions, steel plates for lighting fixtures, etc.
