摘要
在实验室将 Si-Cr-Nb钢轨钢与 UIC90 0 A、U71 Mn等钢轨钢进行了对比试验研究。各钢种的力学性能测定和热模拟试验表明 ,Si-Cr-Nb钢轨钢具有良好的强韧性 ,适合于全长淬火 。
The comparative tests between Si Cr Nb rail steel and UIC900A and U71Mn are carried out in laboratory. The results of various mechanical property measurement and thermal simulation test show the strength and the toughness of Si Cr Nb rail steel is better, suitable for whole length quenching and the weldability of which is also better.
