RESEARCH AND DEVELOPMENT OF Nb-BEARING STEEL PLATES FOR PRESSURE VESSELS IN CHINA

摘要：

　　The present paper provides a brief introduction to the development history and current grades of steel plate for pressure vessels in China.Niobium microalloy technology for pressure vessel steel plates,which could refine the as-rolled microstructure,inhibit the grain growth during heating and soaking,improve creep resistance by stable precipitates at elevated temperature,strength steel due to fine precipitates after tempering,increase hardenability,improve steel toughness and weldability,has been discussed.The research and application of Niobium in C-Mn steels,low temperature steels,Cr-Mo steels,as well as high strength steels for pressure vessels in China have been introduced in detail.
