Abstract

Abstract: Hot rolling with different deformations for high aluminum 316L stainless steel was carried out, and the effects of which on microstructure, tensile properties and fatigue properties of the 316L steel were studied using SEM and TEM characterization, as well as tensile and fatigue testing methods. The results show that the hot rolled high aluminum 316L stainless steel has austenitic and ferritic microstructure, while the strength and fatigue life of the tested steel can be improved by hot rolling deformation. With the increase of rolling deformation, the ferrite volume fraction and dislocation density in the tested steel microstructure increase gradually, the tensile strength and fatigue life increase obviously, while the elongation decreases. The tensile strength and fatigue life of the tested steel with 75% hot rolling deformation reach their maximum values, which are 937.6 MPa and 3.8 ×10⁷ times, respectively, while the elongation reachs the minimum value of 42.7%.
