August 18, 2026 Kester 817 Soldering Flux Inorganic Acid Solution
Kester 817 Soldering Flux is an inorganic acid flux formulated as an active solution of inorganic salts for general all-purpose metal joining. Manufactured by Kester, this specialized flux provides maximum wetting capability for non-electronic soldering applications involving difficult-to-solder metals.
Technical Features
Kester 817 is characterized as a mild flux with a very active solution specifically developed for soldering stainless steel and nickel-chrome alloys. The formulation can be applied using various heating methods, including soldering irons, torches, ovens, induction coils, or resistance tools.
Because of the corrosive nature of inorganic acid formulations, residues must be thoroughly removed with water after soldering to prevent ongoing corrosion caused by residual chloride salts. Due to these corrosive properties, this product is strictly precluded from use in electrical or electronic applications.
Key Product Highlights
- Alloy Compatibility: Specially developed for soldering nickel-chrome and stainless steel alloys.
- Maximum Wetting: Active inorganic salt solution delivers superior wetting on difficult metals.
- Versatile Heating: Compatible with soldering irons, torches, ovens, induction coils, and resistance tools.
- Water-Washable Residue: Post-solder flux residues can be completely removed using water.
