Super Duplex Steel 2507 S32760 (F55) Hex Bars are designed for demanding industrial applications where both high strength and superior corrosion resistance are required. This grade combines the benefits of austenitic and ferritic stainless steels, resulting in excellent resistance to pitting, crevice corrosion, and stress corrosion cracking. The F55 designation ensures enhanced mechanical properties while maintaining long-term durability in aggressive environments. These hex bars are widely used in chemical processing, offshore, and marine applications.

Manufactured to precise standards, S32760 hex bars offer consistent quality and dimensional accuracy. The production process involves controlled heat treatment and forging to achieve uniform microstructure and high tensile strength. This ensures that the hex bars can withstand extreme mechanical stress without deformation or failure. Additionally, the material maintains its integrity under cyclic loading, making it suitable for critical engineering applications where reliability is paramount.

Super Duplex Steel 2507 hex bars exhibit outstanding corrosion resistance due to their high chromium, molybdenum, and nitrogen content. These elements form a passive oxide layer on the surface, protecting the steel against chloride-induced corrosion. This makes it an ideal choice for applications in seawater, brine, and chemical environments. The alloy’s ability to resist localized corrosion ensures long-term performance, reducing maintenance costs and extending the life of industrial equipment.
