S-Weld Passivator is a powerful oxidising solution for the passivation of stainless steel, duplex steel and Inconel alloys. S-Weld Passivator can be used following pickling, grinding or mechanical polishing of stainless steel to ensure a passive surface is obtained prior to installation or commissioning of the final product. As with liquid pickling solution a bath/emersion passivation method produces the best results as it reaches all areas of the surface.
