结构改进的热轧薄钢板

[中文适用范围]： 本国际标准适用于表 1 所列牌号的结构质量热轧钢板，通常不使用微合金元素制备。 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，适用于螺栓、铆接或焊接结构。 该产品是在宽带钢轧机上生产的，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（包含在 ISO 3573[1] 中）、重新轧制为冷轧产品的钢材或指定为耐候钢的钢材，提高了耐大气腐蚀性能。 [外文原描述]： 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.
