Steel Authority of India (SAIL) has supplied 4,000 tonnes of special steel for INS Nilgiri, which was commissioned on January 16, 2025. INS Nilgiri, INS Surat, and INS Vaghsheer were the three Indian Navy warships commissioned at the Naval Dockyard in Mumbai.
The special steel provided by SAIL includes DMR 249A grade hot-rolled (HR) sheets and plates. SAIL's Bokaro Steel Plant contributed about 2,000 tonnes of HR sheets and plates, with an additional 1,600 tonnes and 400 tonnes of plates supplied by the Bhilai and Rourkela steel plants, respectively. INS Nilgiri, the lead ship of the Project 17A stealth frigate class, represents a significant advancement over the Shivalik-class frigates.
SAIL is India’s largest steel producing company. The company is among the five Maharatnas of the country’s Central Public Sector Enterprises. The company has five integrated steel plants, three special plants, and one subsidiary in different parts of the country.
