摘要/Abstract

摘要： 通过对国内外制造的600 MW以上的超(超)临界发电机组用Super304H钢(%:0.07～0.13C、17.0～19.0Cr、7.5～10.5Ni、0.001～0.010B、0.3～0.6Nb、2.5～3.5Cu、0.05～0.12N)管材的制造工艺和质量分析,得出为获得较好的高温力学性能和耐腐蚀性,最佳的成分控制为:≤0.08%C、≤3.0%Cu、0.0002%S、Nb/C≥5、Nb/(C+N)≥2。文中叙述了Super304H钢管的热处理,冷加工变形量,喷丸等关键工艺。

Abstract: With analysis on producing process and quality of Super304H(0.07～0. 13C,17.0～19.0Cr,7.5~ 10.5Ni,0.001~0.010B,0.3~0.6Nb,2.5~3.5Cu,0.05~0. 12N)steel tube for more than 600 MW ultra- supercriti- cal electric power unit made at home and abroad, it is obtained that in order to get better high temperature mechanical prop- erties and corrosion resistance,the optimum chemical composition control is ≤0.08C,≤3.0Cu,0.0002S,Nb/C≥5, Nb/(C+N)≥2.The key processes such as heat treatment,cold working deformation and shot peening for Super304H steel tube are presented in this article.
