Description 270-275
New varieties of high-strength rebar Fe500S with superior seismic resistance properties have been developed to meet
future needs of construction in seismic prone areas. Billets have been produced by standard steel making process route
(BOF-LF-CC) with the exception of chemical designing, which has been uniquely improvised so as to reduce the alloying
cost. Reheated billets have been rolled into final TMT rebars by varying the operation parameters such as velocity and
quenching rate. Chemical properties, surface morphology, and mechanical properties of the thus-produced TMT rebars have
been studied by OES (spark analysis), optical microscopy, tensile, and hardness tests. Cost analysis has shown attenuation in
the alloying cost by a margin of Rs. 855 per ton. Mechanical properties as evaluated from tensile tests have also yielded a
positive outcome in the form of better tensile strength (UTS/YS ratio) and hardness. All the results have been compared with
the Indian Standard IS 1786:2008.
