What is the thermal conductivity of steel?

The thermal conductivity of steel varies depending on the alloy.

(It also varies as the temperature of the metal.) Stainless steels

are generally only about a third as thermally conductive as carbon

steel. Copper is about ten times as thermally conductive as carbon

steel. If a "number" is somehow required for the thermal

conductivity (k) of steel, try k = 40 W/m K (at about

25 oC).
