Abstract In order to stabilize and optimize industrial production process，the microstructure and mechanical properties of wire rod of high-chromium ferrite stainless steel 446 （/%：0.035C，0.50Mn，0.025P，0.003S，0.49Si，25.25Cr，0.030N） were researched in different annealed processes. The results showed that the optimum mechanical properties were achieved for the 446 wire rod after annealing at 800 ℃ for 4.5 h，with tensile strength of 540 MPa，yield strength of 377 MPa，area reduction of 86.5% and grain size rate of 7.5. As the grain size rate influenced less in trial temperature range of 780-880 ℃，the coarse crystal of high-chromium ferrite stainless steel was hard to be refined by annealing process. However，the grain would be growing extremely when the annealing temperature exceeded 920 ℃. The grain coarsening of 446 wire rod can be restrained effectively and the grain size rate can reach 10.0 with controlling the mass percent of N for 0.08%-0.20%.
