The self-repair mechanism of stainless steel
Stainless steel has a unique feature: It is self healing. Due to the alloying elements in the stainless steel, a thin, transparent "passive layer" is formed on the surface.
Even if the stainless steel surface is scratched or damaged otherwise, this passive layer, which is only a few atoms thick, instantaneously reforms under the influence of oxygen from air or water.

MICROPEENŽ treatment of metal surface
The MICROPEEN® treatment is a method by which the metal surface is hammered with spherical glass beads. The process occurs under fully controlled conditions. The surface is uniformly treated till saturation. Depending on the chosen process conditions the surface of the treated metal is becoming clean, smooth and harder, while a compressive stress is built up in a thin surface layer.
