标准摘要
[中文适用范围]: ISO 9327 的本部分适用于由表 1 所列钢材制造、厚度不超过 250 毫米(部分不超过 500 毫米)的锻件和轧制或锻造棒材,并按照 ISO 9327-1 中给出的规范进行交付。 2 ISO 9327 的本部分涵盖以下数据: a) 表 1 中的限值 — 根据铸造分析的化学成分; ——室温拉伸性能; ——冲击性能; ——交货时通常热处理条件的说明; b) 表 2 中给出的铸造分析极限值的允许产品分析公差; c) 表 3 中的最小高温保证强度值(见 ISO 9327-1:1998 的 C.4); d) 表4中估计的平均应力断裂性能; e) 表 5 中 1% 塑性应变的估计平均强度值。 [外文原描述]: 1.1 This part of ISO 9327 applies to forgings and rolled or forged bars in thicknesses up to 250 mm (partly up to 500 mm) manufactured from the steels listed in Table 1 and to be delivered according to the specifications given in ISO 9327-1. 1.2 This part of ISO 9327 covers the following data: a) in Table 1 the limits for the chemical composition according to the cast analysis; the tensile properties at room temperature; the impact properties; the indications on the usual heat treatment condition at the time of delivery; b) in Table 2 the permissible product analysis tolerances on the limiting values given for the cast analysis; c) in Table 3 the minimum elevated temperature proof strength values (see C.4 of ISO 9327-1:1998); d) in Table 4 the estimated average stress rupture properties; e) in Table 5 the estimated average strength values for 1 % plastic strain.
