标准摘要
[中文适用范围]: 本文件规定了一种通过比较目视分析对铸铁中石墨微观结构进行分类的方法。 本文件的目的是提供有关石墨分类方法的信息。 它无意提供有关铸铁类型和牌号是否适合任何特定应用的信息。 特定材料等级主要由机械性能决定,对于奥氏体铸铁和耐磨铸铁,则由其化学成分决定。 对石墨形状和尺寸的解释不允许对满足相关材料标准中规定的要求提供统计上有效的声明。 [外文原描述]: This document specifies a method of classifying the microstructure of graphite in cast irons by comparative visual analysis. The purpose of this document is to provide information about the method of graphite classification. It is not intended to give information on the suitability of cast-iron types and grades for any particular application. The particular material grades are specified mainly by mechanical properties and, in the case of austenitic and abrasion resistant cast irons, by their chemical composition. The interpretation of graphite form and size does not allow a statistically valid statement on the fulfilment of the requirements specified in the relevant material standard.
