摘要
研究了成都无缝钢管厂生产的P91钢管的常温和高温力学性能。研究表明：温度和应力对材料的高温强度和持久强度有很大的影响；国产P91钢管具有较好的高温力学性能，与国外同类产品性能一致。讨论了P91钢管的常温低周疲劳特征。
An investigation was made into the machanical properties under ambient and ele-vated temperatures of the P91 steel tubes produced by Chengdu Seamless Steel Tube Plant,Theresult shows that both temperature and stress impose tremendous influence upon high-temperaturestrength and sustained strength of the material. The home-made P91 steel tubes are in possessionof proper high-temperature properties which are in compliance with those of tubes of the samekind made abroad. Also discussed in the paper is the said tube's low-cycle fatigue characteristicsunder ambient temperature.
