摘　　要：Heat-resistant ferritic stainless steels are widely used in many high-temperature applications such as power plants,automotive exhaust manifolds and solid oxide fuel cell interconnects due to their low price,low coefficient of thermal expansion,high thermal conductivity,high thermal fatigue resistance,high creep performance and excellent corrosion resistance.High-temperature strength,formability,high-temperature oxidation resistance and creep performance are the main evaluation criteria for the application.With the development of relevant industries,higher requirements are proposed for the performance of ferritic stainless steels.Therefore,the development of a new generation of heat-resistant ferritic stainless steel has received extensive attention.In this presentation,we summarized the research progress of heat-resistant ferritic stainless steels including high-temperature strength,formability,high-temperature oxidation resistance and creep performance.Meanwhile,some suggestions are given for alloy composition design and microstructure optimization.The future research direction of heat-resistant ferritic stainless steels also prospected.
