NICKEL ALLOY BALLS
MONEL
Monel is widely used in the chemical, pharmaceutical, maritime, oil, textile and paper industries.
It is highly resistant to (caustic) alcaline solutions, sea water and diluted sulphuric acid.
Monel-K (500) is often used when higher hardness and resistance are needed.

HASTELLOY
This material is universally used in valves and pumps where the greatest resistance is required to corrosion caused by strongly oxidising acids.
Hastelloy-C276 is resistant to strongly oxidising agents such as chlorine, nitric, acetic, formic, phosphoric, sulphuric and hydrofluoric acids, zinc chloride and ammonium solutions, water-based solutions containing chlorine or hypochlorites and acid solutions of ferric and cupric salts.
Hastelloy-D is exceptionally resistant to any concentration of sulphuric acid, up to its boiling point.
