| Abstract: | This paper introduces the trial-production, production technology, chemical composition, mechanical properties and microstructure of remained heat treatment ribbed steel bars at Ma Steel. Taking Q235 steel and 20MnSi steel as tested materials, the effects of chemical composition and production technology on the properties of remained heat treatment ribbed steel bars were investigated. Besides, the change of aging properties of the ribbed steel bars was also observed. It is suggested that the application of remained heat treatment ribbed steel bars should be extended in China. |
