Present works describe the development of Fe‐Cr‐Co‐Mo alloys with favorable {110}〈100〉 texture, which will lie along the transverse direction (TD) of the rolled strips. The studied alloy composition is Fe‐30 wt. % Cr‐15 wt. %Co‐3 wt. % Mo‐0.1 wt. % Mn‐0.05 wt. % S. The magnetic properties of the alloys have been enhanced along the TD and the best magnetic properties obtained with TD alloys are Br=1.2 T (12.0 kG), iHc=82 kA m−1 (1025 Oe), and BHmax=56 kJ m−3 (7.0 MGOe). The favorable texture is developed by secondary recrystallization, caused by a mixture of rolling and annealing. It can be considered that the process adopted in this investigation is useful for mass production of Fe‐Cr‐Co alloys with high energy products, without forming a columnar structure or a single crystal.
