Abstract
The objective of the present study was to calculate physical property values for steels from their chemical
compositions for subsequent use in mathematical models of the fluid flow, heat transfer and shell
solidification in the continuous casting mould. Values of the following properties of steels are calculated
for temperatures between 298 K and 2 000 K; Heat Capacity (Cp) Density (ρ) Thermal conductivity (k) and
diffusivity (a) Electrical resistivity (R) Viscosity (η) Surface (γm) and Interfacial tension (γmsl). In addition temperatures
of transitions (Liquidus Tliq, Solidus Tsol) and various solid state transitions were also calculated.
Ferritic and austenitic phases of Carbon - and stainless steels are both covered. The associated software
is available on the following websites (i) http://www.mxif.manchester.ac.uk/resources/software (ii) https://
