Steel is alloyed with various elements to improve physical properties and to produce special properties such as resistance to corrosion or heat. Specific effects of the addition of such elements are outlined below: Carbon (C) The most important constituent of steel.
Metallographic grinding and polishing insight | Struers
Grinding is the first step of mechanical material removal. Proper grinding removes damaged or deformed surface material, while limiting the amount of additional surface deformation. The goal is a plane surface with minimal damage that can easily be removed during polishing in the shortest possible time.

Fillers for papermaking: A review of their properties,
This observation implies that much of the effect of fillers on paper’s optical properties must be partly due to their influence on paper’s microstructure, rather than just their mere presence. In other studies the optimum particle size for light scattering efficiency has been found to be a function of particle shape (Gill and Scott 1987).
