Unveiling the Robustness of SUPER DUPLEX 2507

In the realm of high-performance materials, Hangnie Super Alloys Co., Ltd. stands at the forefront, presenting the SUPER DUPLEX 2507—a super duplex stainless steel that epitomizes strength and corrosion resistance. Engineered for the most demanding applications, this alloy is a testament to the company’s commitment to excellence.

Composition and Resistance

The SUPER DUPLEX 2507 is a harmonious blend of 25% chromium, 4% molybdenum, and 7% nickel. This robust combination ensures an outstanding resistance to chloride pitting and crevice corrosion, thanks to its high molybdenum, chromium, and nitrogen content. The duplex structure of the alloy imparts it with an exceptional resistance to chloride stress corrosion cracking, making it a reliable choice for critical environments.

Mechanical Properties and Applications

With its superior mechanical properties, the SUPER DUPLEX 2507 often allows the use of a lighter gauge material to achieve the same design strength as a thicker nickel alloy. This weight reduction translates into significant cost savings in fabrication. The alloy’s low rate of thermal expansion and excellent weldability and workability further enhance its appeal across various industries.

Optimal Usage and Limitations

While the alloy’s prowess is undeniable, it is recommended to limit its usage to temperatures below 600° F (316° C). Prolonged exposure to higher temperatures may affect its toughness and corrosion resistance.

Industrial Applications

The SUPER DUPLEX 2507 finds its place in a myriad of applications, including:

•  Desalination Equipment: Its resistance to chloride-rich environments makes it ideal for water treatment facilities.

•  Chemical Process Pressure Vessels, Piping, and Heat Exchangers: The alloy withstands the harsh conditions of chemical processing.

•  Marine Applications: The sea’s corrosive nature is no match for the 2507′s robustness.

•  Flue Gas Scrubbing Equipment: It excels in combating the acidic and chloride-laden environments of gas scrubbing systems.

•  Pulp & Paper Mill Equipment: Resisting the organic acids present in these industries, the 2507 ensures longevity and reliability.

•  Offshore Oil Production/Technology and Oil and Gas Industry Equipment: The alloy’s strength and corrosion resistance are crucial in the extreme conditions of oil and gas extraction.


Hangnie Super Alloys Co., Ltd. takes pride in offering the SUPER DUPLEX 2507, a product that not only meets but exceeds the industry standards for durability and performance. As a trusted supplier, Hangnie ensures that each lens reflects the pinnacle of innovation in stainless steel technology.
