Our stainless steel soldering fluxes are RoHS compliant.

Superior No. 71 is a high-activity Zinc Chloride flux formulated for situations where a general-purpose soft soldering flux is not strong enough for badly oxidized or difficult-to-solder metals like stainless steels, Monel, High-Chrome alloys and Inconel. No. 71 is our most active flux for soldering stainless steel. No. 71 contains Zinc Chloride, Ammonium Chloride, Hydrochloric Acid and a fluoride activator. Fluoride etches glass, and thus this flux should not be used on parts where glass etching would be an issue. (If glass etching is an issue, Contact Us. We have other liquid fluxes for stainless steel soldering, such as our No. 75, Acid Soldering Flux.) The post-solder residues from No. 71 are water-soluble. 

Superior No. 78 is a gel form stainless steel soldering flux. Due to its high viscosity, the gel flux does not migrate upon heating, providing a more restrictive solder flow. The post-solder residues from No. 78 are water-soluble.

Superior No. 79 is an Acid-Free flux formulated for stainless steel, high-chrome alloys and other general soldering applications.

Superior No. 144 is a unique Water-Soluble paste flux. This soldering flux was specifically formulated for situations where dispensing is required for a stainless steel soldering application. No. 144 can be precision dispensed either automatically or manually, or applied with a brush or similar implement. No. 144 is also an excellent choice for badly oxidized copper. The post-solder residues from No. 144 are water-soluble.
