The procedure
Electrochemical process: a computer-controlled electrochemical process; no color or pigments – coat of lacquer or any other coating as well – are applied, the transparent chromium oxide layer is built up.
Interference effect: The interference effect is used; depending on the thickness of the applied chromium oxide layer, the composition of the light spectrum and the angle of view, different colour effects develop.
Stainless steel character: Due to the small thickness of the chromium oxide layer, the structure of the colored surfaces has an undiminished effect; retained are not only the functional material properties, but also the optical quality inherent in the stainless steel.
Resistance of colored stainless steel surfaces
Corrosion resistance: The corrosion resistance of the basic material used is decisive. Although the chromium oxide layer built up during the colouring process is an improvement from corrosion-technical view, in principle a material quality is to be chosen according to the expectable strain.
Resistance to light, weathering and aging: Coloured stainless steel surfaces, do not age, they do not get chapped, do not bleach and do not peel off.
Temperature resistance: The coloured surface is resistant to temperatures up to 200 ° Celsius. Short-term exceeding of temperature of about 100° Celsius can generally be endured, but persistent discolourations occur during continuous exceedances.
Mechanical resistance: The chromium oxide layer built during coloring is organically bonded with the base material and is elastic. Deformations (bending, edging, pressure forming and deep drawing), which do not affect the basic material itself, do not damage the surface. The resistance to abrasive stress is limited due to the low layer thickness of the interference film.
