Alloy 20 Ferrule Fittings Manufacturer in India
Sawariya Metal Industries is a manufacturer, supplier, stockist and exporter of Alloy 20 Ferrule Fittings in different sizes, grades, specifications and finishes for industrial and engineering applications.
Alloy 20 Ferrule Fittings are compression-type tube fittings that use front and back ferrules to grip the tube and create a reliable, leak-tight seal without welding.
Alloy 20 (UNS N08020) is designed for excellent resistance to sulphuric acid. Alloy 20 (UNS N08020) is a niobium-stabilized nickel-iron-chromium alloy with copper and molybdenum, developed for excellent resistance to sulphuric acid and other aggressive chemical environments.
Typical applications for Alloy 20 Ferrule Fittings include chemical processing, sulphuric acid plants, pharmaceutical, petrochemical, pickling equipment, food processing, synthetic fibre plants, heat exchangers and general engineering.
Key Features of Alloy 20
Sulphuric Acid Resistance
Developed specifically for sulphuric acid service.
Stress Corrosion Resistance
Good resistance to chloride stress corrosion cracking.
Niobium Stabilized
Reduced risk of carbide precipitation during welding.
Good Fabricability
Suitable for forming, machining and welding.
