OUR PASSIVATING
Passivating is the chemical treatment of a stainless steel surface with a mild oxidant such as a citric acid and nitric acid base solution, this is typically done to remove any free iron from the surface of the metal, which enhances the corrosion resistance of the stainless steel surface and accelerates the re-formation of the passive […]

Pickling paste used to remove the black oxide marks of burn seal left during welding of Stainless Steel. Also pickling chemical descaling is typically used to remove oxide layers resulting from welding heat trating and other high temperature operation. All of these oxide layers rust a spot are generally referred to as ‘scale’ and must be […]

There are two types of Electropolishing facility. Direct electropolishing Electropolishing after mechanical polishing Commercial applications for electropolishing have been in use since the early 1960’s. Electropolishing is a process by which metal is removed from a work piece by passage of electric current while the work is submerged in a specially-designed solution. The process is essentially the reverse of […]
