2507 Stainless Steel Pipe/Tube

Product Overview: The Power of Two Phases


Duplex stainless steels combine the best properties of both austenitic and ferritic steels. Compared to standard 316L, they offer twice the mechanical strength and significantly higher resistance to localized corrosion.

Type 2205 (UNS S32205/S31803): The workhorse of the duplex family, providing excellent resistance to stress corrosion cracking (SCC) in chloride environments.

Type 2507 (UNS S32750): A Super Duplex grade designed for highly corrosive conditions, such as seawater desalination and subsea oil & gas applications.

The Advantage of Partnering with Our Supply Chain


Expertise in Metallurgical Balance


The performance of Duplex steel relies on the perfect 50:50 balance between austenite and ferrite phases.

Precision Annealing: We strictly monitor the solution annealing process to ensure the correct microstructure, preventing embrittlement or loss of corrosion resistance.

Advanced Lab Testing: We offer Metallographic Examination and G48 Pitting Tests to guarantee reliability in aggressive offshore and chemical environments.


Rigorous Quality Control for High-Pressure Use


Mechanical Integrity: Every batch undergoes comprehensive testing—including Tensile, Hardness, Flaring, and Flattening tests—ensuring safety under high-pressure conditions.

100% NDT Testing: Utilizing both Eddy Current and Ultrasonic testing, we ensure every meter of pipe is free from internal and surface defects.


Reliable International B2B Service


Integrated Solutions: From precision cutting and beveling to internal Ra control, we provide "installation-ready" products to save your site labor costs.

Seamless Logistics & Compliance: With extensive experience in markets across Southeast Asia, the Middle East, and Russia, we ensure all documentation (EN 10204 3.1 MTC, CO, etc.) is perfectly prepared for smooth customs entry.
