Duplex Alloy Coil
High Strength & Lightweight: Approximately double the yield strength of conventional austenitic grades (e.g., 304/316), enabling lighter yet durable designs.
Superior Corrosion Resistance: Excellent resistance to chloride stress corrosion cracking, pitting, and crevice corrosion, especially in marine and chemical media.
Grade Flexibility: Available in standard duplex (e.g., 2205/UNS S32205), super duplex (e.g., 2507/UNS S32750), and lean duplex grades to suit varying mechanical and environmental needs.
Controlled Consistency: Uniform gauge, surface quality, and metallurgical properties ensured through precise rolling and annealing processes.
Ideal for offshore and marine equipment, chemical processing components, heat exchanger fins, structural fabrications, and industrial machinery parts. We offer custom slitting, edge conditioning, and full material certification with traceability to support seamless integration into your production process.
We offer high-performance alloy materials including Inconel, Monel, Hastelloy, Nickel, and Duplex, with all products compliant with ASTM/ASME international standards. Through precise chemical composition control and full-thickness performance consistency assurance, our products meet diverse industrial needs—from aerospace hot-end components and deep-sea corrosive environments to chemical reaction vessels and new energy equipment. Coil form is particularly suitable for continuous automated production scenarios, supporting efficient stamping, forming, and welding processes. While maintaining excellent corrosion resistance, high-temperature strength, and fatigue resistance, our coils significantly enhance the economic efficiency of our customers' production workflows.
In order to ensure product quality, we will arrange professional personnel to check product quality, packaging, weight, hardness, etc., according to customer requirements of product specifications, looking for high-quality and cheap cooperative factories in China, to provide customers with one-stop procurement services and quality assurance.
Excellent packaging: waterproof paper and plastic film + iron cover + at least three strapping straps + strapping straps fixed on iron or wood pallets can effectively protect products from corrosion and various climate changes during transportation. Generally speaking, we ship from Shanghai, Tianjin, Qingdao and Ningbo ports. We have worked with many experienced shipping companies for a long time to find the most suitable mode of transportation for you.
