The proposed steel plant to be set up under a joint Venture (JV) between ArcelorMittal and state-run SAIl will come up at a major auto cluster in India. The NRI billionaire lakshmi Mittal-led firm said last month that it has tied-up with SAIl to set up an automotive steel plant at an estimated Rs5,000 crore investment. "MoU signed with SAIl on May 22 to study feasibility of creating JV for constructing cold rolled (CR) and hot-dip galvanised (HDG) automotive steel production facility in one of the major auto clusters in India," ArcelorMittal said in an investor presentation. India has four major auto clusters -- Pune-Chakan belt in Maharashtra, in the outskirts of Chennai in Tamil Nadu, Sanad in Gujarat and the Gurgaon-Neemrana belt spread across Haryana and Rajasthan.
