Manufacturer, Supplier & Exporter of Duplex 2003 Spool
Duplex 2003 (sometimes referred to as UNS S32003) is a lean duplex stainless steel specially formulated to deliver a strong, cost-effective alternative to austenitic grades such as 316/L. As a "spool," it refers to prefabricated piping assemblies including pipe segments, elbows, tees, reducers, and flanges, welded together in a controlled shop environment. These spools are ready for installation, minimizing on-site welding, reducing labor, and ensuring better quality and alignment. For industries in India, such as chemical plants, water treatment facilities, and desalination units, Duplex 2003 spools provide a high‑performance, cost-efficient piping solution..
Duplex 2003 Spool, also referred to as UNS S32003 in international standards, is a lean duplex stainless steel that combines excellent strength with moderate corrosion resistance. Spools are pre-fabricated piping assemblies, including pipes, elbows, tees, and flanges, which are welded together in controlled environments. This design significantly reduces on-site welding, enhances project efficiency, and ensures precise alignment during installation. Riddhi Siddhi Impex, as a trusted domestic supplier, specializes in providing these spools to various industries across India, ensuring high-quality materials that meet stringent engineering standards..
Duplex 2003 is characterized by a duplex microstructure consisting of approximately equal amounts of ferrite and austenite phases. This dual-phase structure provides superior strength compared to conventional austenitic stainless steels. The alloy offers high yield strength, typically around 450 MPa, and tensile strength exceeding 655 MPa, allowing engineers to use thinner-walled spool components without compromising safety or performance. Its lower nickel content compared to other duplex grades makes it a cost-effective alternative while retaining essential corrosion resistance..
The chemical composition of Duplex 2003 includes 19–22% chromium, 3–4% nickel, 1.5–2.0% molybdenum, and nitrogen content around 0.14–0.20%. This combination provides moderate resistance to pitting and crevice corrosion, making it ideal for chemical, marine, and water-treatment applications where chloride exposure is moderate. The nitrogen content stabilizes the duplex structure, improving both mechanical strength and resistance to localized corrosion, while molybdenum enhances resistance against corrosive media...
Mechanically, Duplex 2003 exhibits excellent load-bearing capabilities. Its high yield and tensile strength make it suitable for high-pressure piping systems and industrial applications. The elongation of 25% or more ensures that the material can endure mechanical stresses and minor deformations during installation. These properties, coupled with its moderate corrosion resistance, make it a versatile material for piping spools used in chemical plants, desalination units, and process industries throughout India..
