本文件规定了在6.3中给出的通常交货条件下，表2和表3（化学成分）和表4和表5（机械性能）中给出的等级和质量经改进的耐大气腐蚀热轧扁钢和长钢产品的交货技术条件。表1给出了本文件中规定的钢种和质量的产品的厚度。表1-不同钢种的产品形式，其耐大气腐蚀性能取决于其厚度[未复制表格]本文件中规定的钢不打算进行热处理，除非交付的产品在交货条件+N下交付。应力消除是可接受的。在+N条件下交付的产品可以在交付后热成型和\/或正火（见第3条）。

This document specifies technical delivery conditions for flat and long products of hot rolled steels with improved atmospheric corrosion resistance in the grades and qualities given in Tables 2 and 3 (chemical composition) and Tables 4 and 5 (mechanical properties) in the usual delivery conditions as given in 6.3. The thicknesses in which products of the steel grades and qualities specified in this document can be supplied are given in Table 1. Table 1 - Product forms for the different steel grades with improved atmospheric corrosion resistance depending on their thickness [table not reproduced] The steels specified in this document are not intended to be heat treated except products delivered in the delivery condition +N. Stress relieving is accepted. Products delivered in +N condition can be hot formed and/or normalized after delivery (see Clause 3).
