摘　　要：我公司为某厂生产的水轮机轴产品,调质后硬度未能满足要求。通过调整化学成分,控制合金元素含量,提高硬度值,极大地改善了ASTM A668 CL. E材料各项性能。Hardness of water turbine shaft products after tempering and quenching manufactured by our company was unsuitable for the requirements. By adjusting the chemical compositions and controlling alloy elements contents as well as improving hardness values, various properties of ASTM A668 CL. E material has been upgraded greatly.

关 键 词：水轮机轴 化学成分 力学性能
