I am writing an article for eGullet.com about cookware, and I among the things I hope to do is describe the differences in the thermal properties of various cookware materials. Thus far, I have the following from the Handbook of Chemistry and Physics:
Spec Ht Density Thermal Cond (J/g K) (g/cm^3) (W/cm/K) ------- -------- ----------- Al 0.897 2.70 2.27 Cu 0.385 8.96 4.01 Fe 0.449 7.87 0.80
What I would really like to have is similar and comparable figures for stainless steel and carbon steel in the types that would normally used for cookware**. I understand that specific heat and thermal conductivity change depending on the temperature, so what would really be useful would be numbers that were directly comparable with those I have given above.
**For stainless steel I guess these would be 18/10, 18/8, 302, 304 and
316... I have a feeling that some of these are the same thing(?), but I am not quite sure so any explanation would be welcome.
My thanks to anyone who has such numbers handy and could help me with some information.
