摘要
GB/T 226描述了对结构钢、连铸坯等常用的宏观检验法——酸蚀检验法。就1991版与新版标准的差异进行了对比说明,发现新版标准中基本每个章节都有不同程度的修改,主要包括试样的截取、加工、腐蚀等方面,这样的修改使标准能更好地被运用到实际工作中。
The common macroscopic examination method for structural steel and continuous casting billet by etching was described in GB/T 226.The differences between the new edition standard and the old edition standard in 1991 were contrasted.It was found that all of the chapters had different degree of change basically in the new edition standard,including sampling,processing and corrosion,so as to apply the standard for practical work.
