Clean Weld Discoloration on SST


We are looking for a chemical that will cleanup the weld bluing on stainless steel parts. We're not sure on the application process - paste or liquid. Any information in this area would be helpful.

Hello Don,

We provide equipment to electrolytically remove heat tint from stainless steel weld areas. In addition the process will remove Ferrous corrosion and passivate the area to meet the requirements of QQ-P-35 [link is to free spec at Defense Logistics Agency,] and AMS2700 [link by ed. to spec at TechStreet].

Best regards,
