Abstrct:Microalloy V was used successfully at 32mm HRB500E ribbed steel in JISCO.By adoption of precipitation, solid-liquid strengthening and fine-grain strengthening mechanisms of V, the HRB500E was developed successfully through ad-justing composition and process basis on HRB400E.performance indicators of 32mm HRB500E have some margin compared with GB, with the Rel is higher than 40MPa,Rm is higher than 60MPa,A%is higher than 6%,Agt is higher than 3%. Yield ratio and yield strength meet GB requirements.
