Effect of hot rolling parameters on recovery mechanism in 436 (17%Cr, Nb-Mo) ferritic stainless steel

Ferritic stainless steel (FSS) grades are widely used for applications that require high strength and corrosion resistance. Their cost versatility in the market have attracted a lot of interest from both industry academic research. Despite their desirable properties, these steels experience surface defects as result microstructural evolution evolves due to softening mechanism. The current study simulated roughing hot rolling processes AISI 436 (17%Cr, Nb-Mo) FSS effects inter-pass time strain on precipitation behaviour mechanisms FSS. resulting microstructures were investigated using SEM-EBSD technique. results revealed Particle Stimulated Nucleation new grains during which promoted recrystallisation accumulation. Stored deformation energy was found increase with an interpass strain.
