Hot-rolled steel sheet in coils of higher yield strength with improved formability and heavy thickness for cold forming. | Status: Superseded, Withdrawn

1 Scope 1.1 This International Standard applies to continuous 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, which includes microalloying elements, to provide improved formability. The steel can be treated to achieve inclusion control. The product is intended for applications where parts are to be fabricated requiring better formability than is provided by normal high-yield-strength steel sheet. It is generally used in the as-delivered condition. This product is commonly produced on a wide strip mill. Because of the combination of higher strength and improved formability, it is possible to obtain savings in mass along with better weldability (see 4.4).
