is stainless steel conductive ?

Stainless Steel is a relatively weak conductor of electrical current compared to other metals. It does conduct electrical current, but the conductivity is significantly lower. The electrical conductivity depends on the composition, namely alloying elements.

Stainless steel is made up primarily of iron and alloys such as chromium or nickel. Addition of nickel and chrome to stainless reduces electrical conductivity. These alloying ingredients create a protective layer on top of the stainless steel that enhances its resistance to corrosion but also reduces it's electrical conductivity.

In terms of practical applications, stainless is used for electrical and electronic devices, but is not an efficient conductor. Copper or aluminum are better materials. When electrical resistance is critical, designers and engineers tend to choose other materials. But stainless steel can be used in places where electrical conductivity may not be a major concern. It is valued for corrosion resistance, strength and durability.
