    DEVELOPMENT OF D652 LOW-ALLOY HI-STRENGTH SEAMLESS STEEL TUBE

    • 摘要: 介绍了D652新钢种的研制及采用该钢种试制起重臂用冷轧(拔)无缝钢管的工艺研究情况。比较了不同工艺对管材组织及性能的影响,提出了优化的工艺路线,满足了产品要求。

       

      Abstract: Introduced in the paper are the development of the new D652 steel and the research concerning the trial production of the cold-rolled (drawn) seamless tubes for lifting arm with the said steel. Based on comparision concerning effects by different processes on the structure and properties of the tube, the optimum process flow has been worked out so as to meet relevant product creteria.
