New Delhi, Jul 22 : Chandrayaan 2 which began its mission to moon on Monday has been built with the special steel supplied by the public-sector Steel Authority of India Ltd. (SAIL), that fulfilled the stringent requirements and specifications of the Indian Space Research Organisation (ISRO) for its ambitious moon mission.
For the Chandrayaan 2, SAIL’s special quality sheet has been used in the Cryogenic Engine (CE20). SAIL has supplied special quality stainless steel from its Salem Steel Plant for the purpose, a company release said here.
As a part of this initiative, scientists from Liquid Propulsion System Centre (LPSC) of ISRO and the SAIL team at its Salem Steel Plant have closely collaborated and successfully rolled the stainless steel coils at Salem.
This hot rolled coil of 4 mm thickness was further cold rolled to 2.3 mm thickness as required by ISRO. This 2.3 mm thick sheet has been used in the Cryogenic Engine (CE20) of Chandrayaan mission
In this, Electro Slag Remelted (ESR) and forged slabs conforming to ICSS-1218-321 austenitic stainless steel slabs provided by ISRO has been successfully hot rolled in the Hot Rolling/Steckel Mill at SAIL’s Salem Steel Plant.
Earlier as well, SAIL has collaborated with ISRO to provide quality steel for the country’s prestigious and indigenous space missions and with this breakthrough SAIL is optimistic of leveraging other aerospace grades of stainless steel for the space launch vehicle components in future.(UNI)
