It holds that main causes promoting crack on martensite stainless steel are gross martensite and crystal boundary carburet and secondary phase distributed along crystal boundary.

文章认，粗大体组织、晶界碳化物以及沿晶界分布“第二相”组织是促使体不锈钢产生裂纹主要原因。

In this paper, we used 20 high-quality carburet structure steed, recommended the experiment on abrasive water jet metal-cutting and others affecting metallurgic structure.

本文以20＃优质碳素结构钢件，介绍了磨料水射流切割与其它方法切割对金相组织影响验。
