The 2507 Super Duplex Bar is a high-performance stainless steel bar designed for superior strength and corrosion resistance. Manufactured according to international standards such as ASTM A276, ASTM A479, and EN 10088, this alloy combines high chromium, molybdenum, and nitrogen content, offering excellent mechanical properties and long-term reliability.
Every batch of 2507 Super Duplex Bars is subjected to strict quality control, including chemical composition testing, mechanical property verification, and third-party certification. Material Test Certificates (MTCs) are provided, ensuring traceability and compliance with global industry standards. With outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking, it is ideal for the most demanding applications.
Key Features & Advantages
Superior Corrosion Resistance: 2507 Super Duplex Rod exhibits excellent performance in chloride-rich and acidic environments, outperforming standard austenitic and ferritic stainless steels.
High Strength: Offers higher yield and tensile strength compared to conventional stainless steel bars, making it suitable for structural applications.
Durable & Stable: Maintains consistent performance over long-term use, reducing maintenance costs.
Certified Quality: Compliant with ASTM and EN standards, with third-party testing reports and MTCs available.
Applications
The 2507 Super Duplex Bar is widely used in industries where both mechanical strength and corrosion resistance are required:
Oil & Gas: Pump shafts, piping, and heat exchanger components.
Marine Engineering: Ship propeller shafts, offshore platform structures.
Chemical Processing: Storage tanks, reactors, valves.
Food & Pharmaceutical: Processing equipment and structural components requiring hygienic conditions.
