The ferritic stainless steels are materials used in several segments due to the excellent combination of mechanical properties and corrosion resistance. The mechanical properties of these alloys are strongly dependent on the microstructural characteristics and crystallography texture. The aim of this experimental study is to investigate the roles of the grain size of the hot rolled sample on the development of the microstructure, texture and formability of ferritic stainless steel. The main elements of chemical composition of the steel under investigation were 16.0 %Cr, 0.021 %C, 0.024 %N and 0.35 %Nb. Coarse and fine grains samples were cold rolled up to 90% thickness reduction and annealed at 880°C with soaking time of the 24 s. The texture measurements were performed by Electron Backscattered Diffraction (EBSD) in the longitudinal section. The formability was evaluated by the R-value and planar anisotropy (Δr) in tensile tests. The final microstructure after annealed was more homogenous for smaller initial grain size sample. This condition was favorable to develop γ-fiber, with sharpness intensity in 111121 components. The highest R-value and smallest planar anisotropy was obtained for a {111}/{001} ratio around 5.37. On the other hand, coarser initial grain size sample had showed a heterogeneous microstructure and texture, performing badly in mechanical tests (anisotropy).

Abstract OUTOKUMPU MODA 430/4016 is a 16% chromium ferritic stainless steel that combines good mechanical properties with good corrosion resistance and heat and oxidation resistance up to 815 °C (1500 °F). It is the most commonly used ferritic stainless steel grade and can be used to replace type 304 austenitic stainless steel in certain applications. It is best suited for mildly corrosive environments. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-1340. Producer or source: Outokumpu Oyj.

430 Stainless Steel

In this research, influence of annealing process on microstructure and mechanical performance of Nb-Ti-stabilized 430 ferritic stainless steel were investigated. In order to obtain the optimal annealing process, metallographic observation, SEM detection and tensile test were carried out. It is found that the microscopic structure is composed of fine and uniform isometric recrystallization grain after annealing. Optimum microstructure and mechanical properties can be achieved while annealed at 950 °Cfor 90 seconds. The annealed sample can obtain the optimum microstructure and mechanical properties under such annealing process. The yield platform is eliminated and the average plastic strain ratio is further improved to 1.269, which reflected a well deep drawability of the Nb-Ti-stabilized 430 ferritic stainless steel compared to SUS 430 stainless steel.
