AP1000环行起重机车轮材料国产化替代试验研究

Study on substitution test for localization of wheel materials of AP1000 polar crane

针对AP1000环行起重机车轮材料的国产化,文中对比中外两种材料(AISI-1070和65Mn)的化学成分和力学性能,研究材料之间的差异,并通过试验验证,最终确定了车轮的替代材料为65Mn。

In view of localization of wheel materials of AP1000 polar crane,the paper compares the chemical composition and mechanical property of two kinds of materials（ AISI 1070 and 65Mn） from China and foreign countries,analyzes their differences,and finally determines to use 65 Mn as the substitution material of the wheel after test verification.
