What is stainless steel surface passivation treatment? What does passivation do?

Passivation is the last and key step in the chemical cleaning of stainless steel. Boiler after pickling, water washing, rinsing, metal surface is very clean, very active, easy to suffer from corrosion, so it must be immediately passivation treatment, so that the metal surface after cleaning to generate a protective film, slow down corrosion. Use: pickling passivation treatment for stainless steel, remove all kinds of dirt, rust, oxide skin, welding spots and other dirt, the surface becomes uniform silver white after treatment, greatly improve the corrosion resistance of stainless steel, suitable for various types of stainless steel parts, plates and equipment. It is simple to operate, convenient to use, economical and practical. At the same time, it adds efficient corrosion inhibitor and fog suppressant to prevent metal from over-corrosion and hydrogen embrittlement and inhibit acid fog. Especially suitable for small complex workpiece, not suitable for paste, superior to similar products in the market.
