摘　　要：The effect of Ti and Nb on the recrystallization and the recrystallized grain size of the hot-rolled plates and cold-rolled sheets of ultra low carbon and nitrogen （ULCN） Cr18 ferritic stainless steel （FSS） is investigated. The results show that the recrystallization of hot-rolled plates and cold-rolled sheets with 0.29% Nb is delayed,and the recrystallized grains are significantly refined.The effect of Ti and Nb on the recrystallization and the recrystallized grain size of the hot-rolled plates and cold-rolled sheets of ultra low carbon and nitrogen （ULCN） Cr18 ferritic stainless steel （FSS） is investigated.
