摘　　要：低合金结构钢是三代环吊的关键受力件使用的主要材料,文中对AP1000环吊吊钩材料的国产化问题进行了研究,对比中外2种材料(ASTM-A668-4340/45和34Cr2Ni2Mo)的化学成分和力学性能,并进行了试验验证,最终确定了吊钩的替代材料34Cr2Ni2Mo.Low-alloy structural steel is the main material used for the key force-bearing parts of the third generation polar crane.In this paper,the localization of AP1000 ring crane hook material is studied,and the chemical composition and mechanical properties of two kinds of materials(ASTM-A668-4340/45 and 34Cr2Ni2Mo)at home and abroad are compared,and verified by experiments.Finally,34Cr2Ni2Mo is selected as the substitute material of the hook.
