Abstract

The aim of the present work was to study the effect of the finishing rolling temperature on interpass recrystallization promotion of an Nb-stabilized AISI 430 steel, via torsion tests simulation of a Steckel mill. The occurrence of interpass recrystallization was investigated by interrupting the tests before predetermined passes and analyzing the samples via electron backscatter diffraction (EBSD). The results revealed that interpass recrystallization can be promoted by decreasing the initial hot rolling temperature; which results in increased strain hardening during the passes and therefore, increased stored energy for recrystallization. The torsion test results concurred with those obtained by EBSD measurements. Furthermore, an optimum temperature range of 900–840 °C was found to promote interpass recrystallization during hot rolling.
