Ferritic stainless steels, which are a group of stainless steels whose production and consumption are constantly increasing thanks to their constantly increasing design volumes and wide range of uses, are relatively inexpensive stainless steels compared to other stainless steel qualities due to the alloying elements they contain. Ferritic stainless steels, which make up 26% of the entire stainless steel market: they are produced cheaper compared with the production of other stainless steels due to the alloying elements they contain. Because of its ferrite structure, its hardness first decreases and then hardens depending on time and temperature in the heat treatment applied after deformation. When this situation occurs, it causes undesirable mechanical properties to occur and therefore the produced material goes out of the standards which is something we don’t desire. In this study, the heat treatment conditions necessary for the production of AISI – 430 quality stainless steels within the standards are explained with their energy diagrams. It was then examined and modeled with various regression models.
