Hi. Does anyone have the Electromagnetic and Thermal Properties of AISI 4340 or 4330 or 4325. Anything close.

    Its related to some induction hardening simulation work I am doing so need:

    1. Thermal Conductivity (W/mK)
    2. Heat Capacity (J/kgK)
    3. Electric conductivity (S/m

    I am able to find data in the handbooks and online for most materials but not Ni Cr Mo low alloy steel.

    Hi Darren,

    In the absence of any experimental data ,you can probably get reasonable estimates based on CALPHAD predictions for these properties.
