摘要
介绍了我国工程机械液压缸材料现状,对标国外同行业材料成分与性能,分析了添加V元素对热轧钢管及冷拔钢管性能的改善,开发出满足工程机械液压缸需求的高强韧性材料。分析认为:单一添加V元素可以制造出系列低成本高强韧性材料;后续准备通过国家标准的制定在工程机械行业推广应用添加V元素的高强韧性新材料。
Described here in the article is the current state of the materials as used for the home-made engineering machinery hydraulic cylinder.Compared with applicable foreign standard for the chemical composition and properties of the said materials,the improvement of properties of both the hot-rolled steel pipe and the cold-drawn one by addition of Element V is analyzed,based on which the hi-toughness materials as meeting the needs of the engineering machineryused hydraulic cylinder is developed.It is regarded via relevant analysis that series low-cast and high toughness materials can be produced by means of just adding Element V only;subsequent matters concerns preparation of applicable national standard in a bid to spread up and apply the above mentioned new V-added hi-toughness materials in the engineering machinery field.
