On the BSE, the company's scrip hit a low of Rs 83.5, down 2.17 per cent over its previous close, soon after the start of market hours today.
It continued to trade in the range of Rs 84.70-83.50 in early trade, which was higher than the floor price.
At the floor price of Rs 83, a 5 per cent stake or over 20.65 crore shares in SAIL could garner around Rs 1,714 crore to the exchequer.
As much as 10 per cent of the offered shares have been reserved for retail investors, who can buy stocks worth up to Rs 2 lakh in the share sale. A minimum of 25 per cent of the issue size would be reserved for mutual funds and insurance companies.
Also, a 5 per cent discount on the bid price would be given to retail investors.

HSBC Securities, Deutsche Equities and J P Morgan India are among the six merchant bankers advising the SAIL stake sale.
While the new government assumed power in late May, there have been no PSU share sales so far in the current fiscal.
