Heat treatment of steel is more than just meeting a hardness specification.
It must  also produce a desirable residual stress state, proper metallurgical phase distribution, and correct dimensions. The DANTE® software aids the heat treater and designer in predicting the effects of chemistry and process variables on these parameters.

DANTE Utilities comprise a set of software tools that are used to derive mechanical
constants, kinetics parameters, and heat transfer coefficient data from experimental data. MEC-FIT determines DANTE mechanical constants from rate and temperature controlled tension and compression tests. DIL-FIT determines phase transformation kinetics parameters for austenite formation and austenite decomposition to ferrite, pearlite, bainite and martensite from ASTM Standard A1033 dilatometry tests. JOM-GEN calculates the Jominy hardness curve with accompanying phase fraction curves from DANTE kinetics parameters for a specific steel chemistry. TTT-GEN and CCT-GEN programs calculate isothermal transformation and continuous cooling diagrams using kinetics parameters in the DANTE material database. G_CARB and V_CARB are used to predict carbon and case hardness profiles for gas and vacuum carburizing, or to optimize gas carburizing or vacuum carburizing schedules to produce desired profiles.

DANTE/KIVA uses Sierra Vista Technology's new conjugate gradient solver tuned to
the heat treat class of problems.  The results is a fast, accurate package for solving 3D thermal stress problems that involve carbon diffusion and phase transformations.
