FLAME METALLURGICAL, INC.
This program allows the user to generate a theoretical Jominy curve based on composition. The formula was developed by Erwin Just (Met. Prog., 1969, p.87). Applicable chemistry ranges are shown under the element %.

Input the concentrations of the alloying elements , wt % (example %C=0.20) below. Use 7 for grain size if it is not known:
%C%Mn%Si%Ni%Cr%MoGrain Size
(.08-.56)(.20-1.88)(0-3.8)(0-8.94)(0-1.97)(0-.53)(1.5-11)

( Jominy positions 1/16 inches, Hardness in HRc )
