£3,170.00

Super Duplex Stainless Steel (2507) is a high-performance alloy that offers exceptional corrosion resistance, strength, and durability. This steel grade is particularly suited for demanding applications in harsh environments, where other materials might falter. With its unique combination of chromium, molybdenum, and nitrogen, 2507 exhibits outstanding resistance to pitting, crevice corrosion, and chloride-induced stress corrosion cracking. Its high yield strength, which exceeds 80,000 psi (550 MPa), makes it an ideal choice for fabricating components that require high strength-to-weight ratios, such as those found in offshore oil and gas platforms, desalination plants, and chemical processing facilities. Additionally, the low nickel content of 2507 reduces the risk of sulfidation and nitridation, making it an attractive option for high-temperature applications. The welded joints of 2507 display excellent corrosion resistance, thanks to its low thermal expansion coefficient and high chromium content. This feature enables the steel to maintain its integrity even in the most challenging welding conditions. Furthermore, the steel’s high ductility and impact resistance ensure that it can withstand sudden changes in temperature and pressure without compromising its structural integrity. In terms of machinability, 2507 is relatively easy to work with, despite its high strength and hardness. It can be machined using conventional tools and techniques, although some adjustments may be necessary to accommodate its unique properties. The steel’s excellent weldability and formability also make it an attractive option for fabricating complex components and assemblies. Overall, Super Duplex Stainless Steel (2507) is a versatile and reliable material that offers a unique combination of corrosion resistance, strength, and durability. Its exceptional performance in harsh environments makes it an ideal choice for a wide range of industries, from oil and gas to chemical processing, marine, and power generation.

Description

Super Duplex Stainless Steel (2507) is a highly corrosion-resistant alloy that combines the desirable properties of both austenitic and ferritic stainless steels. It is characterized by its high strength and excellent resistance to localized corrosion, making it an ideal choice for harsh environments such as marine applications, oil and gas production, and chemical processing. With a composition typically containing 25% chromium, 7% nickel, and a significant proportion of molybdenum, Super Duplex 2507 is engineered to perform under extreme conditions, including high temperature and pressure fluctuations.

One of the standout features of Super Duplex 2507 is its impressive pitting and crevice corrosion resistance, which is crucial for components exposed to chlorides and other aggressive media. This attribute is particularly valuable in offshore and coastal applications where exposure to seawater is common. Additionally, the material’s high mechanical strength allows for thinner sections in structural design, thereby contributing to reduced weight and enhanced cost-effectiveness in manufacturing and construction processes.

The production and fabrication of Super Duplex 2507 require careful consideration due to its unique metallurgical properties. It is essential to adopt specific welding techniques that preserve its corrosion-resistant characteristics without compromising the integrity of the material. Post-weld heat treatment is often recommended to ensure optimal performance, and proper handling during fabrication is crucial to avoid issues like sensitization.

Overall, Super Duplex Stainless Steel (2507) is a versatile and robust material that meets the demands of challenging applications across various industries, providing long-term reliability and performance in environments where conventional stainless steels may falter. Its ability to withstand both mechanical stresses and corrosive attacks makes it a preferred choice for engineers and designers looking to enhance the durability and safety of their projects.
