ISO 4995 pdf download.Hot-rolled steel sheet of structural quality 1 Scope 1.1 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. 1.2 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. 1.3 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”. 1.4 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 [1 ] ) or steels to be re-rolled to cold- reduced products, or steels designated as weathering steels, having increased atmospheric corrosion resistance. 2 Normative reference The following normative document contains provisions which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent edition of the normative document indicated below. For undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain registers of currently valid International Standards. ISO 6892:1 998, Metallic materials — Tensile testing at ambienttemperature 3 Terms and definitions For the purposes of this International Standard, the following terms and definitions apply. 3.1 microalloying elements elements, such as niobium, vanadium, titanium, etc., added singly or in combination to obtain higher strength levels combined with better formability, weldability and toughness as compared with non-alloyed steel produced to equivalent strength levels 3.2 hot-rolled steel sheet a product obtained by rolling heated steel through a continuous-type or reversing-type wide strip mill to the required sheet thickness NOTE The product has a surface covered with oxide...
