In fact, stainless steel materials for passivation treatment is just to make it on the surface of stainless steel to generate a very dense, and good coverage, firmly adsorbed on the surface of the passivation film. The passivation film can prolong the rust time of stainless steel, effectively protect the surface of stainless steel, make stainless steel more corrosion resistance.

Stainless steel passivating solution after passivating treatment, will not have any effect on the metal surface; Whether it is the appearance, or the hardness of the surface material. Because stainless steel passivation liquid using nanotechnology and a number of domestic and foreign high-tech research and development, and the passivation film formed on the surface of stainless steel only tomorrow micron, so in the choice of passivation liquid will not worry about the use of the characteristics of stainless steel will change.

In the use of stainless steel passivation liquid, it can mainly be applied to SUS200, SUS300 series of all stainless steel products. At the same time, compared with other passivation liquid phase in the past, the corrosion resistance of 5~20 times, and even fully meet or even exceed JIS, ASTM, GB and other related standards (according to astMB-117 and DINENISO9227 neutral salt spray test standard, 2000H above the beginning of the rust spot, but because of the different material properties, The anticorrosion effect may be different, 200 series material 48~500H,300 series material 72~2000H salt spray test). Passivation liquid belongs to environmental protection, chromium-free passivation liquid; The products also comply with RoHS and eu REACH standards.
