Multifaceted Behavior and Versatility Features of Ferritic Stainless Steels, Part II: Investigating Electromagnetic, Mechanical, and Corrosion Behavior

This comprehensive review, serving as Part II of a two‐part series, investigates the multifaceted relationship among processing, microstructure, and properties in ferritic stainless steels (FSSs). This review assesses the experimental and theoretical studies to deliver an advanced understanding of FSS performance through electromagnetic, mechanical, and corrosion properties. It highlights the material behavior, dictated by the precise control of microstructural evolution. The review scrutinizes how thermomechanical treatments, like cold/hot working and subsequent heat treatment, are instrumental in tailoring grain boundary networks and managing strain‐induced recrystallization. A central finding is the ability to strategically control crystallographic textures, particularly the formation of γ ‐fiber orientation, to manage plastic anisotropy and enhance formability. Furthermore, this work clarifies the critical role of strategic alloying additions in modifying degradation mechanisms. It demonstrates how elements like Nb/Ti effectively suppress the formation of brittle intermetallic phases, thereby improving both mechanical integrity and corrosion resistance, particularly against intergranular attack. Cross‐property linkages are also reviewed, revealing how microstructural features influence magnetic response and link to the material's mechanical behavior. By consolidating these multifaceted visions, this review delivers a foundational framework for rational materials design and process optimization, guiding the development of next‐generation FSS with properties tailored for demanding industrial environments.
