Chrome has about the same conductivity that Stainless does, or at
least from the info I found. 3-15% for Stainless, 19% for chrome,
relative to copper.

For a conductor 102" long with a diameter of 0.625", the following metals have
the following AC resistance at 27 MHz:

Chromium .0194 ohms
Copper .00711 ohms
S. Steel .0451 ohms

************************************************** **********
Chromium .0194 ohms ?
Copper .00711 ohms ?

With these figures Chrome has 36% the conductivity of copper

Stainless steel is definitely more resistive than
you stated. According to your figure SS has 16%
the conductivity of copper. This is not even close.
Standard carbon steel has10% the conductivity.
Stainless is less. 18-8 is 2.5%, 13-cr is 3.5%, and
18-cr is 3%

The conductivity of the above figures on steel and
stainless steel come from the "Metals" properties table,
