Heat of vaporization? Steel.

I have tried to find a good reference for the amount of heat needed to transform x picograms of steel into vapour. I can't find it in my CRC handbook 62nd edition. I have googled, but seem to hit only rather specialized papers that are hard to access.

I need the number to be able to estimate the diameter of a crater caused by a discharge of a 10 nF capacitor through oil film when the capacitor voltage is around 10 V.

Anyone?

Hi Skogsgurra

I found the Latent heat of vaporization for iron to be 6090 kj/kg at this site:-

couldn't find steel though.

Thanks a lot 'fox!

I finally found it on paper in an old text-book. It says 6.8 MJ/kg steel. I think that kind of verifies your number. I'll go with that.

Isn't this site great!?
