Scope: This International Standard applies to hot-rolled steel sheet of high yield stress structural quality with the use of microalloying elements. The product is intended for structural purposes where particular mechanical properties are required. It is generally used in the delivered condition and is intended for structures that may include bolting, riveting and welding. Because of the combination of higher strength and microalloy composition, it is possible to obtain savings in mass, along with better formability and weldability as compared with steel sheet without microalloying elements. The product is produced on a wide strip-mill, not a plate mill. This product is commonly produced in thicknesses from 1,6 mm to 6 mm and 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 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 (ISO 3573), steels to be rerolled to cold-reducing products, steels designated as weathering steels, having increased atmospheric corrosion resistance, or steels having improved formability properties compared with those in this International Standard.
