    Steel Authority of India Ltd’s Rourkela Steel Plant has supplied 30.5 tonne of MDN-250 maraging steel to Indian Space Research Organisation for upcoming Gaganayan project, the first indigenous manned mission to space. RSP ED Mr Gautam Banerjee flagged off the plates in a function organised at the Plate Mill department. The plates rolled from 14 slabs were the first lot of the total order quantity.

Stringent process parameters were followed and representatives from MIDHANI, Hyderabad and Scientists from ISRO were present during the rolling of the 1st phase plates at Plate Mill. The Process chart for the rolling was jointly prepared by Plate Mill and R&C Laboratory of RSP. The slabs were supplied by MIDHANI, Hyderabad. Slabs were inspected and sorted after receiving. Strict heating parameters were also monitored. Extra soaking of a minimum of three hours duration was given inside the furnace for rolling of these slabs. During rolling of these slabs experienced rollers were engaged as these slabs require accurate control during rolling. After rolling, these plates were visually inspected at the cooling bed for their surface finish, thickness, width and length. Then plates were turned over for bottom surface inspection. After the rolled plates were certified by the inspection group of MIDHANI, these were painted before despatching to the destination.

Maraging steel is special quality steel containing nickel, cobalt, molybdenum, titanium and aluminium and is manufactured through vacuum melting process. Rolling of maraging steel requires very stringent process parameters. Generally, any steel with higher strength will have low ductility and vice versa. But the significance of maraging steel is that it has got very high strength to the tune of 5-6 times of mild steel along with good ductility. Maraging steel is being used for the launch vehicle rocket motor casing and for other different defence applications. Maraging steel plates rolled in RSP were also used in the recently launched Chandrayan-II

RSP has been regularly rolling wide plates of maraging steel under a long term contract with Mishra Dhatu Nigam 金属展-冶金展-2020广州巨浪国际金属暨冶金工业展览会-亚洲最大金属冶金展-巨浪展览-2020 China(Guangzhou)Int’l Metal & Metallurgy Exhibition-metal exhibition -metal exhibition Metal exhibition, Metal expo, 2020 Metal exhibition, 2020 Metal expo, China Metal exhibition, China Metal expo, steel exhibition, steel expo, 2020 steel exhibition, 2020 steel expo, China steel exhibition, China steel expo
