Introduction to Super Duplex 2507 Stainless Steel

Super Duplex 2507, also known as UNS S32750, is a high-performance stainless steel alloy that belongs to the duplex family of alloys. It combines the best attributes of both austenitic and ferritic stainless steels, offering exceptional strength and outstanding resistance to corrosion. Super Duplex 2507 is specifically designed for applications where extreme corrosion resistance, high strength, and good weldability are critical.

This alloy is primarily made up of approximately 25% chromium, 7% nickel, and 4% molybdenum, along with traces of other elements such as nitrogen. The high content of chromium and molybdenum, combined with the presence of nitrogen, gives Super Duplex 2507 its superior resistance to pitting, crevice corrosion, and stress corrosion cracking, particularly in chloride-rich environments.

Super Duplex 2507 Stainless Steel Bright Bar

Super Duplex 2507 stainless steel bright bars are high-quality bars that have been polished to a smooth, shiny finish. Bright bars are essential for industries that require an aesthetically pleasing appearance as well as superior mechanical properties. These bars are made from high-strength Super Duplex 2507 material and are commonly used for producing shafts, rods, fasteners, and other structural components.

Key Features of Super Duplex 2507 Stainless Steel Bright Bars:

• Exceptional Corrosion Resistance: Offers superior resistance to pitting, crevice corrosion, and stress corrosion cracking in chloride-rich environments.

• High Strength: With a high yield strength of around 550 MPa and tensile strength of up to 800 MPa, Super Duplex 2507 is ideal for applications that require robust structural integrity.

• Superior Durability: The alloy provides long-lasting performance, even in aggressive environments like seawater or chemical processing.

• Aesthetic Appeal: The bright finish gives the bar a mirror-like surface, which is both functional and decorative.

• Enhanced Wear Resistance: The polished surface helps to minimize surface damage and wear, extending the life of components.
