Superior Flux Superior No. 71 High Activity Stainless Steel Flux
Categories:	Metal; Nonferrous Metal; Solder/Braze Alloy
Material Notes:	Formulated for soldering Stainless Steel and High-Chrome Alloys. Excellent across a broad range of base metals, solders, and temperatures. Exhibits excellent capillary action. Description: Superior No. 71 is a water-based, inorganic-acid flux formulated for soldering stainless steel and other industrial metals. The flux contains Zinc Chloride, Ammonium Chloride, a bi-fluoride, and Hydrochloric Acid. This combination of activators makes this flux active at room temperature where it begins to clean metals and remove oxides. The flux exerts a strong scavenging action to remove oxide coatings and other impurities from the metal surface to produce strong joints. Pre-cleaning is not necessary under most conditions. Applications: Superior No. 71 is excellent for use on Stainless Steel, Monel, High-Chrome Alloys, Inconel, Nickel, Copper, Brass, Ferrous Alloys and many more metals. It is not recommended for Aluminum and Magnesium. Information provided by Superior Flux
