2.25Cr-1Mo-0.25V steel research progress and challenges
摘要
Abstract
2.25Cr-1Mo-0.25V steel,as the core material for high-temperature and high-pressure hydrogen service equipment such as hydrogenation reactors,has garnered significant research attention regarding its weldability,elevated-temperature mechanical behavior,and hydrogen embrittlement susceptibility.This paper reviews recent domestic and international research advancements in microstructural regulation of welded joints,optimization of high-temperature mechanical properties,and hydrogen embrittlement mitigation strategies for 2.25Cr-1Mo-0.25V steel.Studies have revealed that two aspects have emerged as research priorities:the influence mechanisms of welding process parameters coupled with heat treatment schedules on carbide evolution and high-temperature mechanical properties in 2.25Cr-1Mo-0.25V steel,as well as the correlation between hydrogen trap distribution characteristics and hydrogen embrittlement susceptibility in this material.Future research directions include elucidating material property degradation mechanisms under multi-field coupled service environments and establishing lifetime performance prediction models through microstructural regulation strategies.关键词
