ISO 4995:2014适用于表1所列等级的结构质量热轧钢板，通常在不使用微合金元素的情况下制备。该产品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，用于螺栓连接、铆接或焊接结构。该产品是在宽带轧机上生产的，而不是在板轧机上生产的。 本国际标准不包括用于锅炉或压力容器的钢、指定为商业质量或拉伸质量的钢（包含在ISO 3573[1]中）、重新轧制成冷轧产品的钢或指定为耐候钢的钢，具有增加的耐大气腐蚀性。

ISO 4995:2014 applies to hot-rolled steel sheet of structural quality in the grades listed in Table 1, usually prepared without 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 bolted, riveted, or welded structures. This product is produced on a wide strip mill, not a plate mill. This International Standard does not cover steels intended for boilers or pressure vessels, steels designated as commercial quality or drawing quality (covered in ISO 3573^[1]), steels to be re-rolled to cold-reduced products, or steels designated as weathering steels, having increased atmospheric corrosion resistance.
