| Abstract: | This study investigates the influence of silicon content and magnetic annealing parameters on the microstructure, mechanical, magnetic, and corrosion properties of 430 stainless steel, an electromagnetic material requiring improved response time. Samples with varying silicon contents (F, F‐1.5Si, and F‐2.0Si) are treated under different annealing conditions (850AC, 850FC, 760FC, and 760FC‐H2). All conditions produce equiaxed grain structures with precipitates and show good tensile strength and elongation. AC magnetic tests at 10–1000 Hz reveal that higher Si content reduced coercivity (Hc) while enhancing saturation and remanent magnetization (Bm, Br). Air annealing lowers Hc, Bm, and Br in F‐1.5Si, while hydrogen annealing reduces Hc and Br but increases Bm. Although higher Si content increases silicon‐rich phases, it did not improve corrosion resistance. The F‐1.5Si sample forms a thicker passivation layer, enhancing corrosion impedance. Finally, correlations between electrical properties and coercivity confirm the metallurgical mechanisms' critical role in optimizing magnetic behavior. [ABSTRACT FROM AUTHOR] |
