Our product range contains a wide range of Stainless Steel Passivation, Titanum PASSIVATION and Brass PASSIVATION

Stainless Steel Passivation

We are offering stainless steel passivation.The process specified is to "pickle and passivate" - a two step method - in order to create a surface on stainless steel that would be resistant to corrosion. Pickling (or chemical descaling) is done to remove scale and open active surface for passivation. Passivation is done to make the surface more passive and corrosion resistant by loosing its chemical reactivity. Passivation unipotentializes the stainless steel with the oxygen absorbed by the metal surface, creating a monomolecular oxide film. Passivation is the formation of a hard non-reactive surface film that inhibits further corrosion. This layer is usually an oxide or nitride that is a few atoms thick.

Titanum Passivation

We are offering titanum passivation.A possible limiting factor of titanium alloy application in aqueous chlorides can be crevice corrosion in metal to metal joints, gasket to metal interfaces or under process stream deposits. Given these potential crevices in hot chloride containing media, localized corrosion of unalloyed titanium and other alloys may occur depending on ph and temperature .Though titanium is immune to corrosive attack by salt water or marine atmospheres. It also exhibits exceptional resistance to a broad range of acids, alkalis, natural waters and industrial chemicals. In certain condition metal get attacked. Biometrically non acceptable .

Brass Passivation

We are offering brass passivation.The purpose of the treatment is to clean and produce a level of passivation of the surface of brass articles to resist staining by handling residues and atmospheric contaminants.Free from stains and have the color of the brass substrate. It is normally intended as a final process before assembly or packaging. The passivation films produced are extremely thin process consist of cleaning , pickling , and chromate passivation, and hot air drying
