In Atmanirbharta Push ISRO Successfully Qualifies Fourth Stage Engine of PSLV With Indigenous Alternative Material

The liquid engines being flown in the fourth stage of PSLV (PS4) use nozzle divergent made up of imported Columbium (C103) material.An alternate material, Stellite (KC20WN), was proposed for the nozzle divergent realization to achieve Atmanirbharta along with associated cost savings. Stellite is a cobalt based alloy with additions of Chromium, Nickel, Tungsten and Iron.It is a material which
