low alloy steel castings

A new kind of low alloy cast steel that had no noble alloy elements such as nickel and molybdenum was researched.

研究了一种不含钼、镍等贵重合金元素的耐磨低合金铸钢材料,具有足够的淬透性和淬硬性,经油冷淬火和中温回火处理后,硬度大于58HRc,冲击韧性大于22J／cm2,断裂韧性大于35MPa。

The result facilitate the cutting processing of low alloy cast steel (ZG55CrMnMo) in practical Wire Electrical Discharge Machining.

按照正交规划试验表,对电火花线切割加工低合金铸钢-ZG55CrMnMo进行切割试验;分析了工艺参数与工艺指标之间的关系,得出了生产率指标和表面粗糙度指标的数学模型,为实际生产加工切割低合金铸钢锻模提供了依据。

A low alloy cast steel has been selected according to tbe service conditions and the main failure meansof hammers.

根据锤头的服役条件和主要失效方式，设计了一种低合金铸钢锤头材质。
