The characteristics of steel

Steel; acier

A metal alloy composed mainly of iron and carbon, produced by the reduction of iron ore, scrap metal and metallurgical coke.

Conductivité électrique; electrical conductivity

The ability of a material to conduct electricity, expressed in S/m.

Conductivité thermique; thermal conductivity

The capacity of a material to transmit heat, expressed in W/m.K. It is linked to the coefficient of thermal expansion, which is a measure of the variation in dimension of a material as a function of temperature, expressed in 1/K.

Density; relative density

The mass per unit volume of a material, expressed in kg/m ³ . Density can be used to describe the physical properties of a...
