The cementation is a unique process that allows the hardening of steel surfaces without losing the ductility of the core part One of the most old process for hardening of steel surface but largely applied for axles and cams it can be used in brass and copper but its more common in steel Parts made of steel with medium or high percentage of carbon that will suffer severe bending operations
