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
