高屈服应力结构质量的热轧薄钢板

[中文适用范围]： 本国际标准适用于采用微合金元素的高屈服应力结构质量热轧钢板。 该产品适用于需要特定机械性能的结构用途。 它通常在交付状态下使用，适用于可能包括螺栓连接、铆接和焊接的结构。 由于更高的强度和微合金成分的结合，与不含微合金元素的钢板相比，可以节省质量，并具有更好的可成形性和可焊接性。 该产品是在宽幅带钢轧机上生产的，而不是在板材轧机上生产的。 本国际标准不包括用于锅炉或压力容器的钢材、指定为商业质量或拉拔质量的钢材（由 ISO 3573 涵盖）、重新轧制为冷轧产品的钢材、指定为耐候钢的钢材、具有增加的大气强度的钢材。 与本国际标准中的钢相比，耐腐蚀性或具有改进的成形性能的钢。 [外文原描述]： ISO 4996:2014 applies to hot-rolled steel sheet of high yield stress structural quality with the use of microalloying elements. The product is intended for structural purposes where particular mechanical properties are required. It is generally used in the delivered condition and is intended for structures that may include bolting, riveting and welding. ISO 4996:2014 is not applicable to steels intended for boilers or pressure vessels, steels designated as commercial quality or drawing quality (covered by ISO 3573), steels to be re-rolled to cold-reducing products, steels designated as weathering steels, having increased atmospheric corrosion resistance, or steels having improved formability properties compared with those covered by it.
