scope:

This International Standard applies to all grades of continuously hot-rolled steel sheet of higher yield strength with improved formability. The steel is killed, made according to a fine grain practice and has a suitable chemical composition, including microalloying elements, to provide improved formability. The product is intended for the fabrication of parts requiring better formability than is provided by normal high yield strength steel sheet. It is generally used in the delivered condition.

Because of the combination of higher strength and improved formability, it is possible to obtain savings in mass along with better weldability.

This product is commonly produced in the range of thicknesses of 1 mm to 6 mm and in widths of 600 mm and over, in coils and cut lengths.

Hot-rolled sheet less than 600 mm wide may be slit from wide sheet and will be considered as sheet.

NOTE  Hot-rolled sheet up to but not including 3 mm in thickness is commonly known as sheet. Hot-rolled sheet 3 mm and over in thickness is commonly known as either "sheet" or "plate"

This International Standard does not cover steel intended for boilers or pressure vessels, steels designated as commercial quality or drawing quality (covered in ISO 3573), steels designated as weathering steels, having increased atmospheric corrosion resistance, or lower yield strength steels having less formability compared with those in this International Standard (covered in ISO 4995 and ISO 4996).
