Pickling & Passivation on Stainless Steel

Pickling passivation ensures corrosion resistance to components of stainless steel and thus considerably influences their life and usefulness. The corrosion resistance of stainless steel is due to the presence of at least thirteen percent chromium in the alloy. With oxygen, the chromium forms a dense chemically resistant passive layer of chromic oxide protecting the surface of the component against corrosion. The passive layer usually forms again after abrasion. The precondition to corrosion resistance and passive layer is a metallically pure surface with a sufficiently high percentage of chromium. Features: removes built-in corrosion from stainless steel; removes scales, discolouration and ferritic contamination; stops corrosion and restores full corrosion resistance; removes metallic contaminants; oxide scales, rust spots and annealing colours; and gives a flawless, uniform, smooth contamination free, sterile particle free, passive surface.
