GB/T 31922-2015
ActiveHot-rolled steel sheets and strips of higher yield strength with improved formability
改善成形性热轧高屈服强度钢板和钢带
Application Summary AI generated
This standard specifies the technical requirements, dimensions, and testing methods for hot-rolled steel sheets and strips with higher yield strength and improved formability. It is primarily applied in the automotive, construction, and machinery industries for manufacturing structural components that require both high strength and the ability to undergo complex forming processes, such as chassis parts, frames, and heavy-duty equipment. The standard ensures consistent material performance in stamping, bending, and welding applications where enhanced ductility is critical.
