UNS N08120, a member of Fe-Ni-Cr alloy family, is capable to withstand severe high temperature and corrosive environments for applications in chemical, power, waste processing etc. Precautionary measures during the casting process can result in sound casting. For the production of UNS N08120 via casting route, the most common method is the vacuum induction melting process, which is less affordable option for small-scale production. Gaseous elements and impurities may get entrapped during casting. The aim of current research is to produce UNS N08120 alloy sound castings using non-vacuum-based induction melting by adding calcium-based reagents and perform a comparative study. This research uses a novel method to reduce the chances of generation of defects that are caused due to the presence of impurities. Two combinations of chemical-based reagents like CaC 2 , CaO and CaF 2  have been selected and used during the sand-casting process. These identified reagents react with the gases and impurities that exist in the molten alloy, and deplete them. The resulting castings yielded alloy free from microstructural defects. This method has been found effective for removal of unwanted gases and impurities in an easy manner. CaF 2  addition also plays vital role in degassing phenomenon of UNS N08120.
