An analysis of microstructure and mechanical properties of ferritic stainless steel 430 during cold rolling and subsequent annealing

Systematic study on the microstructural evolution and mechanical properties of ferritic stainless steel (FSS) 430 with different annealing processes was carried out in present work. The results show that refinement can be achieved by optimization processes, improving elongation, yield strength, tensile strength FSS 430. An optimal temperature 950 ? is found better homogeneity enhanced among cold-rolled annealed FSSs. During fraction high-angle grain boundaries at to highest, indicating a homogeneous microstructure high recrystallization rate formed inside strips. In addition, hard grains (SF < 0.4) low soft are ?, plasticity material. Overall, benefits thereby materials.
