The Hastelloy Balls are universally used in valves and pumps for the greatest corrosion resistance. This material is resistant to strongly oxidizing substances like chlorine, nitric, acetic, formic, phosphoric, sulphuric, and hydrofluoric acids, water-based solutions containing chlorine, and more. It is also resistant to acid solutions of ferric and cupric salts. Hastelloy Ball is exceptionally resistant to any concentration of sulphuric acid, up to its boiling point.
