Stainless Steel Pickling

Pickling and Passivation process ensures corrosion resistance and removes free ion contamination left on the SS surface from fabricating and machinery. These contaminants are prospective corrosion sites resulting in premature corrosion, ultimately resulting in decline of component if not removed. Corrosion resistance of SS is because of the presence of 13 percent chromium in alloy. The chromium, with oxygen, forms a think chemically resistant passive layer of chromic oxide thus shielding the SS surface against corrosion. The passive layer generally forms again after abrasion. All mechanical treatments damage the topmost layer of components i.e.Structural modifications in top layers of SS,Development of in-built stress
