Hot-Rolled Steel Sheet of Structural Quality - Fourth Edition
 N 4995

Annotation

This International Standard applies to hot-rolled steel sheet of structural quality in the grades and classes listed in Tables 1 and 2, usually without 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 bolted, riveted or welded structures. This 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 will be considered as sheet.

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

This International Standard does not cover steels intended for boilers or pressure vessels, or steels designated as commercial quality or drawing qualities (covered in ISO 3573) or steels to be re-rolled to cold-reduced products, or steels designated as weathering steels, having increased atmospheric corrosion resistance.
