Duplex 2205 Sheets,Plates and Coils
Rose Metal Industries stands as a leading global manufacturer, stockist, and exporter of Duplex 2205 Sheets, Plates, and Coils, delivering high‑performance duplex stainless steel solutions for critical engineering applications. Duplex 2205 (UNS S32205 / EN 1.4462) is a premium-grade, ferritic‑austenitic stainless steel alloy renowned for its exceptional combination of high mechanical strength, superior corrosion resistance, and excellent performance in chloride‑rich and aggressive environments
Our Duplex 2205 Sheets, Plates, and Coils are engineered for durability, structural integrity, and extended service life, making them ideal for industries across India and worldwide. With strong supply capabilities across Tamilnadu, Andhra Pradesh, Karnataka, Telangana, Puducherry (Pondicherry) and the Andaman and Nicobar Islands, Rose Metal Industries supports large‑scale infrastructure, marine, petrochemical, and OEM manufacturing projects.
Duplex 2205 offers nearly double the yield strength of conventional austenitic stainless steels such as 304 and 316, allowing engineers to reduce thickness, lower weight, and optimize material cost without compromising safety or performance. Its high chromium, molybdenum, and nitrogen content provides superior resistance to pitting, crevice corrosion, stress‑corrosion cracking, and erosion—making it especially suitable for coastal regions, offshore structures, and seawater handling systems.
Rose Metal Industries maintains an extensive inventory of hot‑rolled plates, cold‑rolled sheets, wide coils, and slit coils in various dimensions, finishes, and tempers. We also provide value‑added services such as cutting, shearing, polishing, flattening, surface finishing, and customized packaging to meet Indian, Gulf, European, and global export requirements.

Applications
- Desalination plants (RO & thermal units), sea water handling systems — widely used in coastal regions such as ports and facilities across Tamilnadu and Andhra Pradesh.
- Oil & gas (onshore & offshore) — piping, manifolds, pressure vessels, and subsea applications.
- Chemical processing — heat exchangers, reactors, storage tanks where chloride stress corrosion resistance is required.
- Marine engineering and shipbuilding — hull components, deck equipment and fittings—important for shipyards and coastal infrastructure in Karnataka and Telangana regions.
- Pulp & paper, mining, and industrial water treatment plants — for improved service life under corrosive conditions.
Our products are supplied in compliance with international manufacturing standards including ASTM A240, ASME SA240, EN 10088, and ISO specifications. Each batch undergoes strict quality inspection, including PMI testing, ultrasonic testing, hardness measurement, and mechanical validation, ensuring that customers receive material that meets or exceeds global performance benchmark.
Rose Metal Industries has built a strong reputation for supplying Duplex 2205 to critical applications such as desalination plants, refinery equipment, oil & gas pipelines, chemical processing units, pressure vessels, marine hardware, heat exchangers, condenser systems, and paper & pulp machinery. Our materials perform exceptionally well in areas with high salinity and humidity, including Chennai, Visakhapatnam, Mangaluru, Puducherry, and Port Blair.
Frequently Asked Questions (FAQ)
Q1: What is the difference between 304 and 304L?
A: 304L has a lower maximum carbon content (≤0.03%) which reduces the risk of sensitization during welding, making it preferable for heavy gauge welded components. Mechanical properties are similar; choose 304L when welding without post-weld anneal is required.
Q2: Do you provide mill test certificates (MTC)?
A: Yes — Rose Metal Industries issues MTCs and can facilitate third-party inspection and PMI/chemical analysis on request.
Q3: What standards do your round bars comply with?
A: We supply material to customer-specified standards including ASTM A276 / A479 and EN standards (e.g., EN 10088 series) depending on product form and destination requirements.
Q4: Can you supply custom diameters, lengths and surface finishes?
A: Yes — we offer cut-to-length, turned/bright finish, polishing and custom tolerances. Contact sales for lead times and minimum order quantities.
Q5: How should I select 304 vs 316 for corrosion resistance?
A: 304 is suitable for many indoor and mildly corrosive environments. For chloride-rich environments (marine, salt-spray, swimming pools) or higher corrosion resistance needs, consider 316 (higher Mo content). Our sales team will advise based on application.
