BS ISO 13976:2016 pdf download.Hot-rolled steel sheet in coils of structural quality and heavy thickness
1 Scope
This document applies to hot-rolled carbon/manganese steel sheet in coils of structural quality without the use of microalloying elements. It is generally used in the delivered condition and is intended for bolted, riveted or welded structures. The product is produced on a wide sheet mill. The product is intended for structural purposes where particular mechanical properties are required. The steel sheet is produced in a number of grade designations designed to be compatible with differing application requirements. This document does not cover steels intended for boilers or pressure vessels, or steels designated as commercial quality or drawing qualities, or steels rolled to cold-reduced products, or steels designated as weathering steels, having increased atmospheric corrosion resistance, or those products rolled on a plate mill.

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 in coils
steel sheet in coil form manufactured through hot-rolling process where the material was heated before rolling to achieve the required sheet thickness and tolerances
Note 1 to entry: The product has a surface covered with oxide or scale resulting from the hot-rolling operation.
5.3 Chemical analysis
5.3.1 Heat analysis An analysis of each heat shall be made by the manufacturer in order to determine compliance with the requirements given in Tables 1 and 2. On request, a report of the heat analysis shall be made available to the purchaser or the purchaser’s representative. Each of the elements listed in Tables 1 and 2 shall be included in the report of the heat analysis. When the amount of copper, nickel, chromium or molybdenum present is less than 0,02 %, the analysis may be reported as “<0,02 %”.
5.3.2 Product analysis A product analysis may be made by the purchaser in order to verify the specified analysis of the product and shall take into consideration any normal heterogeneity. The product analysis tolerances shall be in accordance with Tables 2 and 3.
