通过调整AF1410钢Mo的质量分数到3.0%，得到试验钢，对试验钢不同时效温度的性能进行了初步的研究。试验结果表明，与AF1410钢相比较，当Mo的质量分数为3%时，试验钢的二次硬化效果显著，在460 ℃时效时达到硬化峰值，峰值硬度为HRC 53.5，比AF1410钢的峰值硬度提高了1.5（HRC）。

The mechanical properties of experimental AF1410 with 30% Mo aged at different temperature were studied. The results indicated that the experimental steel has obvious effects of secondary hardening with a age hardening peak at 460 ℃,and the hardness was higher than that of original AF1410 steel by 15 HRC.
