Chanathip Nickel Alloys & Plates Bangkok is a leading manufacturer of coils from Duplex Steel 2205. The coils are produced under strict quality control with uniform chemical composition, close thickness tolerances, and suitable surface finishes for shaping or further processing.
In the form of hot‑rolled or cold‑rolled conditions, 2205 coils are utilized to produce components requiring superior corrosion resistance and strength. We supply regional and export markets, especially for fabrication into pressure vessel skins, claddings, and marine architectural facades. Tracing of all coils to heat numbers and batch.
The 2205 duplex composition consists of ≈ 22% chromium, 5–6% nickel, 2.5‑3.5% molybdenum, nitrogen ~0.14‑0.20%, with carbon, phosphorus, and sulfur held low.
The yield point of formed sheet from coil is approximately 450 MPa, tensile strength ~620‑700 MPa, elongation ≥25%, and hardness generally ≤ ~290 HB. High pitting resistance to chlorides, crevice corrosion, and stress corrosion cracking is typical. Ductility and toughness are good even at moderately low temperatures. Welding and forming from coil shape is workable with suitable procedures.

Duplex Steel 2205 coils are well suited for round-the-clock production of items such as slitted strips, panels, tube sheets, structural cladding, shipbuilding parts, and architectural facades.They can also be used for pressure lining, chemical plant surfaces, and heat exchanger shells manufacture.
Where the environment exposes them to seawater, acidic or alkaline chemicals, or thermal fluctuation, these coils perform extraordinarily. Factories making HVAC panels, coastal structures, or industrial enclosures take advantage of the high strength and corrosion resistance of the duplex coil. Employing 2205 coils supports efficient forming, bending, and fabricating with minimal wastage.
