K-2 Passivation process is a must and should be followed after every pickling process. It protects and avoids the stainless steel surfaces from further corrosion and contamination. This treatment strengthens the passive layer. The treatment is more important after mechanical cleaning and operations involving a risk of iron contamination since the acid also remove iron impurities from the surface. Consequently, the method could also be referred to as decontamination. As after every acid treatment, rinsing with water is vital. This operation instantly Passivate the stainless steel surface. FEATURES: Passivation is a must after every pickling process. It even prevents water staining caused by poor rinsing of water. Passivation can be done after mechanical treatments such as grinding, brushing, blasting etc. Restore the passive layer on Stainless Steel surfaces that has been damaged during fabrication or usage. APPLICATIONS: All Stainless steel grades of 304, 308, 310, 316, 316L grades, 400 duplex and super duplex.
