标准范围

ISO 4997:2007适用于结构质量等级为CR220、CR250、CR320和CH550的冷轧钢板，通常不使用微合金元素。该产品适用于可能包括螺栓连接、铆接和焊接的结构。它通常在交付状态下用于制造目的，如弯曲、成型或焊接。ISO 4997:2007不包括指定为商业质量或拉伸质量（ISO 3574:1999中涵盖）的钢，根据硬度要求（ISO 5954:1998中涵盖）的冷还原碳钢板，冷-具有更高强度和更高可成形性的减薄钢板（见ISO 13887:2004），或具有更高可成形性的高抗拉强度和低屈服点的冷减薄钢板（见ISO 14590:2005）。

ISO 4997:2007 applies to cold-reduced steel sheet of structural quality in grades CR220, CR250, CR320 and CH550, usually without the use of microalloying elements. The product is intended for structures that may include bolting, riveting and welding. It is generally used in the delivered condition for fabricating purposes, such as bending, forming or welding.ISO 4997:2007 does not cover steels designated as commercial quality or drawing qualities (covered in ISO 3574:1999), cold-reduced carbon steel sheet according to hardness requirements (covered in ISO 5954:1998), cold-reduced steel sheet of higher strength with improved formability (covered in ISO 13887:2004), or cold-reduced steel sheet of high tensile strength and low yield point with improved formability (covered in ISO 14590:2005).
