2.25Cr1Mo0.3V钢具有强度高、抗氢侵蚀、抗氢脆和抗氢致剥离等特点,多用于制造加氢反应器。以往国内采用进口加钒钢板,随着国产钢板质量的提高,不少制造厂尝试使用国产板制造加氢反应器。通过国产加钒钢板板焊式加氢反应器的试制,介绍焊接和热处理的关键技术参数,为今后这类钢板的制造提供借鉴。
2.25Cr1Mo0.3V steel with high strength, resistance to hydrogen erosion, resistance to hydrogen embrittlement and hydrogen stripping characteristics, and more for the manufacture of hydrogenation reactor. In the past, the domestic use of imported vanadium steel plate, with the improvement of the quality of domestic steel, many manufacturers try to use homemade plate manufacturing hydrogenation reactor. Through the trial manufacture of domestic plus vanadium steel plate welding hydrogenation reactor, the key technical parameters of welding and heat treatment are introduced to provide reference for the future manufacture of such steel plate.
