This means that the design will usually have only published values of yield strength, ultimate strength, and percentageelongation.
这就是说，设计人员通常只能利用那些公开发表的屈服强度、极限强度和延伸率等数据资料。

Its physical property is similar to that of spheroidal graphite iron tubes, but some aspects such as elongationpercentage are inferior to the spheroidal graphite iron tubes.
物理性质与球墨铸铁管类似，但在延伸率等较多方面均劣于球墨铸铁管，但灰口铸铁管价格适中。
