Is there such a thing, if so I have never heard of it. I am aware that
its conductivity is not good (3 to 10% of that of copper), depending on
the type, but not conducting - I have never heard of. Anyone?

No such thing, but it can be hard to make a contact if you're using a
multimeter. Stainless is essentially so because of the Chromium content
which forms a hard surface layer of oxide which is non-conducting.

Correct. High electrical and thermal conductivity is an intrinsic
property of metals, it is to do with the way that electrons behave in a
lattice comprised of metal atoms.

About the lowest electrical conductivity of convenient metals is the
alloy, Nichrome. In arbitrary units

Nichrome = 1
Stainless steel = 100
Copper = 200

Thanks both, it is as I thought. Just something someone had said, which
contradicted that understanding.

They were perhaps getting confused with the magnetic properties of SS
in the context of induction hobs?

Of course there isn't. Why do you ask?

A sanity check, after someone argued there was a version of SS which
was an insulator.
