This part of ISO 4950 specifies the chemical composition and the mechanical properties of high yield strength flat steel products supplied in the normalized or/ equivalent condition. For the method of manufacture, acceptance conditions and marking of these products, see ISO 4950-1. It applies to hot-rolled plates, wide strip in coils of width greater than or equal to 600 mm, and with flats in the thickness range 3 mm to 150 mm, in steels supplied after normalizing or controlled rolling, having a minimum specified yield strength of 355 N/mm2 to 460 N/mm2 for thickness up to and including 16 mm. This part of ISO 4950 does not apply to products covered by other standards, such as - flat products from continuous mills (see ISO 4996). - flat products for subsequent forming operations (see ISO 5951). - plates for pressure vessels (see ISO 9328-4
