标准范围

1.1 ISO 9327的这一部分适用于制造的厚度不超过250 mm的锻件和轧制或锻造棒材由表1中给出的细晶粒钢（见注释）制成，并根据表1中给出的规格交付ISO 9327-1。钢分为室温等级（P.），升高的温度等级(PH)，低温等级（PL.），低温和高温等级（PLH。）.注:细晶粒钢在这里被理解为晶粒尺寸为6或更细的钢，根据中的晶粒尺寸图表ISO 643。1.2 ISO 9327的这一部分涵盖以下数据:a)在表1中，根据铸件分析的化学成分；室温下的拉伸性能；交货时通常热处理条件的指示；b)在表2中，对于铸造分析给出的极限值，允许的产品分析公差；c)表3中的最小冲击能量值；d)表4中的最小高温强度值。

1.1 This part of ISO 9327 applies to forgings and rolled or forged bars in thicknesses up to 250 mm manufacturedfrom fine grain steels (see NOTE) given in Table 1 and to be delivered according to the specifications given inISO 9327-1.The steels are classified intoroom temperature grades (P.),elevated temperature grades (PH.),low temperature grades (PL.),low and elevated temperature grades (PLH.).NOTE Fine grain steels are here understood as steels with grain size 6 or finer according to the grain size charts inISO 643.1.2 This part of ISO 9327 covers the following data:a) In Table 1 the limits forthe chemical composition according to the cast analysis;the tensile properties at room temperature;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 impact energy values;d) in Table 4 the minimum elevated temperature proof strength values.
