摘要
研究了25Cr3MoA合金棒材热处理对组织和性能的影响。结果表明:电弧炉加电渣重熔冶炼的25Cr3MoA钢组织均匀、纯净度高;艾氏冲击功与夏比冲击功没有对应关系;WS9-6001组别低温冲击韧性最好;在600℃以下仍保持较好的高温性能;400℃时仍具有较高的高温疲劳强度。
The effect of heat treatment on structure and properties of 25Cr3MoA steel has been studied. The results show that the structure of the steel remelted by electroslag process was homogeneous. Low temperature impact toughness after by WS9-6001 process was better than the of other groups. There was no way to convert Aki into Akv.
