Thermal conductivity of extra deep draw steel

[zpiderman]

Hi,

I'm looking for the thermal conductivity constant for "e-coated extra deep draw steel". Is there an internet source for thermal conductivity constants? Can anyone tell me what e-coated means?

Any information would be very much appreciated.

Thanks,

Z

It will be the same as any steel. Thermal condutivity is an intrinsic propertyn and is unnefected by processing. Minor chemistry variations don't have any impact either.

Corrosion never sleeps, but it can be managed.

If there is some sort of coating on the steel (i.e. e-coating), would that not change the overall thermal conductivity of the whole piece?

I have an oil pan and I want to add a vibration damper on it. To protect the vibration damper from thermal degradation, I need to add insulation between the vibration damper and the oil pan. To calculate the heat transfer rate I need the oil temperature, the pan surface temperature and the thermal conductivity constant of the pan (including the e-coat). If the oil temperature and the pan surface temperature is almost the same how can I calculate the insulation thickness required if dT (Toil - Tpan) goes to zero?

The signficance of ANY layer in the thermal path is dependent on BOTH its thermal conductivity AND its thickness.

What you can do is to replace the e-coat layer in your model with a layer of steel whose thickness results in a thermal conduction equivalent to the e-coat.

The problem is that I don't have any data on e-coat. Is there an industry standard in e-coating?
