具有改进可成形性高屈服强度的热轧薄钢板

[中文适用范围]： 本国际标准适用于具有较高屈服强度和改善成形性能的所有牌号的热轧钢板。 该钢经过镇静，根据细晶粒实践制造，并具有合适的化学成分，包括微合金元素，以提供改进的可成形性。 该产品旨在用于制造需要比普通高屈服强度钢板更好的成型性的零件。 一般在交货状态下使用。 [外文原描述]： 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).
