Multifaceted Behavior and Functional Versatility of Ferritic Stainless Steels, Part I: Applications and Processing, a Review

steel research international, EarlyView.
This review investigates the processing‐microstructure‐property relationships in ferritic stainless steels (FSSs). It highlights advances in deformation behavior, heat treatments, surface modifications, and alloying effects. Theoretical models, including Johnson‐Mehl‐Avrami‐Kolmogorov, Arrhenius, nucleation theory, and diffusion theories, are discussed

Alloy Qualification for Producing Quench and Tempered Plate Steels with Extra‐Heavy Gage

steel research international, EarlyView.
This study develops alloy concepts for ultraheavy steel plates (>100 mm) with ≥690 MPa yield strength. Through dilatometry and Jominy testing, the effects of Mo, Ni, and B on hardenability are quantified. A synergy between 0.5% Mo and 0.5%–1.0% Ni ensures core strength at low cooling rates, while boron microalloying suppresses ferrite and promotes ...
