Stainless Steel Surface Treatment And Maintenance And Patterning

Stainless steel surface treatment methods can be roughly divided into five categories, respectively, rolling surface processing, mechanical surface processing, chemical surface processing, reticulated surface processing, color surface processing. Formed products often mirror, drawing, reticulation, etching, electrolytic coloring, coating coloring, etc. The variety of stainless steel surface treatment provides more choices for bright and durable architectural appearance, and also makes it possible for curtain wall design to explore and develop into higher height and more complex environment.

Although stainless steel plate corrosion resistance, but does not mean that stainless steel will not corrosion, if the stainless steel plate is used and maintained improperly or the use of the environment is too bad, will also occur local oxidation corrosion phenomenon. The corrosion of stainless steel mainly has three forms: chemical corrosion, electrochemical corrosion, stress corrosion. Stainless steel surface passivation film corrosion resistance of weak parts, due to the formation of self-excited reaction pitting reaction, formation of small holes, coupled with chlorine ion close to form a strong corrosive solution, will accelerate the speed of corrosion reaction; There are stainless steel internal intergranular corrosion cracking, all of these, on the surface of the stainless steel plate passivation film will damage. Therefore, the surface of the stainless steel plate must be regularly cleaned and maintained in order to maintain its gorgeous surface and prolong the service life.
