【Abstract】 The properties of hot-rolled reinforcing steel 22MnSiV were systematically studied. Besides satisfying HRB400 in GB1449-1998,the hot-rolled reinforcing steel has excellent propertise such as brittle transition temperature being lower than -40?℃,good deformation-resistance ageing and fatigue behaviour under high deformation and low recycle.Therefore,the hot-rolled reinforcing steel is very applicable for earthquake regions and frigid regions.It is also suitable for reinforced concrete structure.更多还原
