Duplex Alloy Plate
High Strength & Lightweight: Yield strength approximately double that of standard austenitic stainless steels (e.g., 304/316), enabling lighter and more durable designs.
Excellent Corrosion Resistance: Outstanding resistance to chloride stress corrosion cracking, pitting, and crevice corrosion, particularly in marine and chemical environments.
Grade Versatility: Available in standard duplex (e.g., 2205/UNS S32205), super duplex (e.g., 2507/UNS S32750), and lean duplex grades for varying performance requirements.
Cost-Efficient Durability: Extended service life and reduced maintenance needs offer lower lifecycle costs in harsh operating conditions.
Duplex plates are widely used in offshore and marine structures, chemical processing equipment, oil and gas pipelines, desalination plants, and pulp and paper machinery. We provide precision cutting, forming support, and full material certification tailored to your project specifications.
We provide a comprehensive matrix of specialty alloy plates, covering a full range of requirements from high-temperature corrosion resistance to specialized environmental applications. By integrating a standardized production system with flexible customization services, we deliver end-to-end support for global clients—from technical consultation and material selection to processing and distribution.
Utilizing vacuum induction melting combined with electroslag remelting processes and an intelligent hot-rolling line, precise control over alloy composition and rolling temperature is achieved, ensuring highly uniform material microstructure. Equipped with specialized solution treatment and quenching systems, along with advanced laminar cooling and online straightening technology, plate flatness reaches ≤3mm/m. Supported by spectroscopy, ultrasonic testing, and corrosion laboratories, strict adherence to international standards such as ASME and ASTM is maintained, with full traceability documentation for all products, meeting certifications for high-end applications. Additionally, customized services including CNC cutting, edge preparation, and surface treatment are available, providing a one-stop solution for specialty alloy plate requirements.
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.
