Production of 400 MPa Class V-Microalloyed Low Carbon Si-Mn Rebar Steel at Lower Cost Through Industrial Rolling

摘要

In this paper, the rolling tests of V-Fe and V-N microalloyed low carbon Si-Mn reber steels have been anlayzed suing TEM and X-ray. The production cost of V-N alloyed rebar steel is compared with that of V-Fe alloyed.
