ISO 5951:2013 pdf free.Hot-rolled steel sheet of higher yield strength with improved formability
ISO 5951 applies to all grades of 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.
ISO 5951 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).

An analysis of each heat of steel shall be made by the manufacturer to determine the contents of carbon, manganese, phosphorus and sulfur, and the content of other elements giving the specified mechanical strength and formability. On request, this analysis shall be reported to the purchaser or his representative.
A product analysis may be made by the purchaser to verify the specified analysis of the product and shall take into consideration any normal heterogeneity. For killed steels, the sampling method shall be agreed upon between the interested parties at the time of ordering. The product analysis tolerances shall be in accordance with Tables 2 and 3.ISO 5951 pdf download.
