The mechanical properties of the materials are related with the atomic arrangement of their constituent elements. Particularly, the electronic cloud at the surface of steels shows spatial properties of the charge distribution of the metallic crystals. In this work we report the conductivity properties of the electronic cloud in the directions normal and parallel to the surface. These conductivity features are studied through the interaction with an optical field. The reflectance components of the materials are measured and related with the conductivity in the respective directions. We show that for the different Steel samples that were measured, a relation between the hardness and the reflectance components is observed.
