PSU Connect reported that another consignment of MDN 250 slabs supplied by Misra Dhatu Nigam Ltd was successfully rolled into plates in Steel Authority of India Limited’s Bhilai Steel Plant’s Plate Mill on 12th April 2021 for use in the satellite launch vehicles of Indian Space Research Organisation. Midhani slabs weighing 40 tonnes were successfully rolled into 20 numbers of 9.3 mm thick plates. Successful rolling of maraging steel in SAIL BSO Plate Mill was achieved by meticulous planning in association with MIDHANI & ISRO’s Vikram Sarabhai Space Centre.
