【摘要】 本文进行了(C+N)含量对2Cr21Ni12N气阀钢强度性能的试验研究,包括对固溶态和时效态的室温和高温硬度试验,对固溶态和时效态的室温和高温拉伸性能的试验以及对高温持久性能和高温弯曲疲劳性能的影响。随着(C+N)含量的增加,硬度和强度性能都不同程度地提高。更多还原

【Abstract】 In this paper, the effect of (C+ N) content on the strength of 2Cr21Nil2N value steel was b·experi mentally investigated, including hardness test and tensile test at room temperature and Ligh temperature after solid Solution treatment and ageing treatment respectively. The creep rupture strength and bending fatigue at high temperature were also conducted. It has shown that the hardess and strength of the steel increases with the increase of (C+N) content.更多还原
