Stainless Steel Duplex 2205 pipe fittings combine a dual-phase microstructure—roughly equal parts austenite and ferrite—to deliver remarkable strength, corrosion resistance, and stress corrosion cracking resistance. These features make them ideal for demanding applications in chemical processing, oil & gas, marine environments, and desalination plants.
Mcneil Instruments is a leading manufacturer, supplier, and exporter of Stainless Steel Duplex 2205 pipe fittings in India. With advanced manufacturing facilities and full compliance with international standards, Mcneil delivers reliable and high-performance fittings to clients worldwide.
What Makes SS Duplex 2205 Unique
Duplex 2205 has an alloy structure with 22% chromium, 5–6% nickel, and 3% molybdenum, along with nitrogen added for enhanced strength and corrosion resistance. This results in:
Superior resistance to pitting, crevice, chloride stress corrosion, and chloride-induced stress cracking.
High mechanical strength, approximately double that of standard austenitic stainless steels.
Cost-effective designs due to reduced material thickness requirements without compromising performance.
Manufacturing & Quality Control
Raw Materials: Procured in accordance with ASTM A815 standards.
Forming: Produced into fittings such as elbows, tees, reducers, and caps using forging or seamless forming techniques.
Heat Treatment: Solution annealed and quenched to stabilize the duplex microstructure.
Finishing: Includes machining, threading, and pickling to ensure professional delivery.
Testing & Inspection: Includes dimensional checks, hardness testing, tensile testing, NDT (UT/RT), and PMI. All products include Mill Test Certificates (EN 10204) and IBR approval as needed.
