Hardenability curves

The underlying models are valid for a limited range of chemical composition, which is displayed with. Within the validity periods, the user can generate as many hardenability curves as they like and export them from the system - the standard display corresponds to the mean value analysis The hardenability calculation is part of the StahlDat SX standard version.

Calculation of hardenability

Calculate forehead quenching hardness (Jominy test) from the chemical analysis
