A maximum tensile stress of 313 MPa is generated after 90° bending, which has exceeded the yield strength of Type 316L stainless steel. It is well known that the tensile residual stresses contribute to fatigue crack development in weldments even under compressive cyclic loading, and they are also considered to be the main reason for the initiation and propagation of stress corrosion crack in welded IHIMU- a A Fully Automated Steel Plate Bending Line heating is a steel plate bending technique for making desired non-developable surfaces. The technique combines plastic deformations caused by local thermal stresses during the heating of steel plates.
