I am associated with development of a high temperature iron base super alloy with following chemistry ;
carbon 0.04 max
Mn 0.50max
Si 0.50max
Cr 14.5
Ni 31.0
Ti 2.7
Mo 0.7
Al 1.9
Nb 0.70
we are trying to make this material through air melting in induction furnace ,ladle refining ,VOD followed casting and then vacuum arc remelting .
