Abstract Scope This work developed new heterostructured and antimicrobial stainless steels (HS&ASSs) to overcome the infection rate of multiple diseases while increasing the service life of stainless steel components. The HS&ASSs were designed to combine all the recognized strengthening mechanisms of metallic materials. Four different low-cost and scalable processing routes were compared. The HS&ASSs resulted in heterostructured lamella structures composed of soft lamellar coarse grains, harder ultrafine-grained regions, multiple defects, and the occurrence of strain-induced phase transformation. The HS&ASS showed an improvement of up to six times in yield strength compared to its homogeneous counterpart (1100 MPa vs. 175 MPa) while keeping reasonable ductility. The antibacterial effectivity of the HS&ASSs was proven by killing 55 to 72% of E. coli bacteria after 6 hours of contact. The new HS&ASSs are feasible for biomedical, structural, and food-processing applications.
