In this study,the influence of annealing processes for cold-rolled sheets on the microstructure and mechanical performance of ultra-pure 430 ferritic stainless steel was investigated.Thermo-Calc calculation,organization observation,SEM detection,and tensile tests were used to discern the optimal annealing process.It is found that the microstructure is made up by the fine and uniform recrystallized ferritic grains after annealing.The optimum annealing process for ultra-pure 430 stainless steel is 950 ℃ for 90 s.After annealing,the stainless steel can obtain the optimum rnicrostructure,recrystallization texture,and mechanical properties.
