摘要
澳大利亚进口的旱地免耕播种机开沟器的材质是一种成分与３０ＣｒＭｎＳｉＮｉ２ＭｏＡ相近的中碳低合金钢，显微组织是针状贝氏体＋少量马氏体。６５Ｍｎ钢经激光表面相变处理后具有良好的耐磨粒磨损性能。
Australia opening shares are made of the cast steel with chemical composition similar to 30CrMnSiNi2MoA domestic steel, their microstructure consists of needle like bainite and small amounts of martensite. 65Mn steel with laser surface treatment which has outstanding wear abrasion property is one of materials those can be substituted for the Australia cast steel to make opening shares.
