ISO 5951:2013适用于屈服强度更高、成形性更好的所有等级热轧钢板。该钢是镇静钢，根据细晶粒实践制造，具有合适的化学成分，包括微合金元素，以提供更好的成形性。该产品用于制造比普通高屈服强度钢板具有更好成形性的零件。通常在交付状态下使用。 由于结合了更高的强度和更好的成形性，因此有可能在获得更好的焊接性的同时节省质量。 ISO 5951:2013不包括锅炉或压力容器用钢、指定为商业质量或图纸质量的钢（ISO 3573涵盖）、指定为耐大气腐蚀性增强的耐候钢，或与ISO 5951:2013中的钢相比，具有较小成形性的低屈服强度钢 2013年（涵盖在ISO 4995和ISO 4996中）。

ISO 5951:2013 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 5951:2013 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 ISO 5951:2013 (covered in ISO 4995 and ISO 4996).
