摘　　要：2.25Cr-1Mo-V钢广泛地用于制造高温高压临氢的承压设备。ASME规范案例2605-1提供了针对该种材料的蠕变-疲劳寿命设计方法。用一个设计实例来阐述该案例的思路和设计方法,并给出了一些提高结构蠕变-疲劳寿命的措施。2. 25Cr-1Mo-V steel has been employed in manufacturing pressure vessels servicing under high pressure temperature and hydrogen exposure condition. An approach for designing of creep-fatigue life has been provided in ASME Code Case 2605-1. A design example was introduced to elaborate the thought and method of the case,and some measures to extend the creep-fatigue life of structure were put forward.
