Measured surface roughness parameters of the samples of S355J2 steel with different surface treatmen

Measured surface roughness parameters of the samples of S355J2 steel with different surface treatment：

Composition of S355J2 steel：

Sandblasting causes more intensive surface deformation of s355j2 steel, that is responsible for the increase of dislocations and defect numbers, and for higher thermodynamic differences between local surface micro areas in comparison to ground surface. This inhomogeneity is then reflected in non-uniform coating formation. Crystal nucleation and further growth is preferentially present in the micro areas with increased inner energy (small residual stresses after sandblasting). Katalor Enterprises has established a full set of strict quality control system,advanced manufacturing technics and equipments.
