Known for its precision engineering, advanced manufacturing techniques, and stringent quality control, the company ensures that every fitting delivers outstanding performance, providing dependability and long service life. Their Duplex 2205 Tube Fittings are built to withstand demanding environments, especially those with high pressure, corrosive materials, and fluctuating temperatures. Dedicated to customer satisfaction and technical excellence, Al Vishwas Nickel Alloys supplies dependable, affordable tube fitting solutions that comply with international standards.
Duplex 2205 Tube Fittings are made from a carefully balanced chemical composition, containing roughly 22% chromium, 5–6% nickel, 3% molybdenum, and regulated nitrogen. This blend produces a two-phase ferritic-austenitic microstructure that delivers outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking. In terms of mechanical properties, Duplex 2205 offers high tensile and yield strength, remarkable fatigue resistance, and strong impact toughness, even at low temperatures. These traits guarantee that the tube fittings preserve their structural integrity and enduring reliability in tough industrial applications involving high stress and harsh environments.
