RESEARCH AND DEVELOPMENT OF Nb-BEARING STEELS FOR LOW TEMPERATURE SERVICE PRESSURE VESSELS

摘要：

　　The paper provides a brief introduction of Niobium microalloy technology,which could refine the as-rolled microstructure,inhibit the grain growth during heating and soaking,strength steel due to fine precipitates after tempering,increase hardenability,improve steel toughness and weldability.The research and application of Niobium-bearing steels for low temperature service pressure vessels,such as Al-killed C-Mn steel and Ni steels have been introduced in detail.
