| Abstract |
The effect of Ti/C+N ratio of type 409 stainless steel on the microstructure of the steel after annealing was investigated. The annealing experiments were carried out using batch annealing and continuous annealing process. The optimum Ti/C+N ratio of the steel was 10 minimum in order t.o obtain fully ferritic structure after continuous annealing. In the case of the lower Ti/C+N ratio(below 10), the hot rolled stainless steel should be applied to batch annealing process to avoid the formation of martensite after continuous annealing process. The optimum condition of continuous annealing was about 3 min at 950℃. |
