Nkhoma et al. [22] compared the hot compression behavior of AISI 304 and 321 austenitic stainless steels and concluded that the AISI 321 steel is softer than AISI 304 steel during deformation in the temperature range of 800–1200 °C. Their work was mainly focused on the mathematical analysis of the hot flow curves and deriving relationships
