The pickling process mainly includes dipping pickling method, spray pickling method and acid cream rust removal method. The general use of dipping pickling method, mass production can use spray method. Is electroplating, enamel, rolling and other processes of pre-treatment or intermediate treatment.

Stainless steel pickling passivation solution ID4008 is our company in the original pickling passivation solution based on the upgrade of a new variety. Characterized by the environmental protection of organic acid oxidant as the main agent, adding polymer rare earth ingredients, high efficiency corrosion inhibitor and catalyst, etc. It is a new kind of environmental protection high-tech material, which does not contain toxic halogen F compounds.

This product is colorless and transparent with light smell. Widely used in SUS300 series austenitic stainless steel (SUS303, 304, 316, 316L, etc.) and other workpieces in the process of forming, assembling, welding, such as rust, spot, oil, black and yellow oxide scale removal and at the same time to the stainless steel work pieces for a comprehensive passivation, greatly improve the corrosion resistance of stainless steel work pieces. Really achieve pickling, passivation two in one effect.

After stainless steel pickling passivation solution ID4008 processed stainless steel workpiece surface will produce a beautiful silvery white passivation film. The passivation film is compact and beautiful, and the corrosion resistance potential can be increased by more than 700mV.
