DEVELOPMENT OF HOT-ROLLED REINFORCING STEEL 22MnSiV
-
摘要: 系统的研究了热轧带肋钢筋22MnSiV各项性能,其各项性能不仅达到GB1449—1998中HRB400的要求,还有其特性:脆性转变温度低于-4 0℃、抗形变时效,高应变低周疲劳性能好。因此,特别适用于地震区、寒冷地区;也适用于钢筋混凝土结构。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.
