Super Duplex components are high-alloy duplex steels containing a mixed structure ferritic and austenitic. A super duplex round bar is produced using high contents of nickel, chromium and molybdenum with moderate additions of other elements. The super duplex 2507 round bar is versatile and is highly resistant to corrosion and oxidation in high stress conditions. UNS S32760 round bar offers good mechanical stability in pitting and stress corrosion cracking prone environments. Super Duplex Stainless Steel Round Bar has more tensile and torsional strength as compared to the normal austenitic grades. F53 round bar is strong with a density of 7.8 g/cm 3 and melting point of about 1350 o C. UNS S32750 round bar is of density 7.8 g/cm 3 and melting point of about 1350 o C. Bars of our team can be provided in the individual sizes and profiles to fit the project requirements.

The flat form Super duplex bar has a rectangular cross-section commonly used in the construction industry. Super Duplex hollow bar is furnished with or without a weld seam. Surface finishes are black, bright, polished, rough or even matt. Within the application of the super duplex stainless steel bar, cold-working may be performed on the bar following the hot rolling to enhance the strength and overall corrosion. Each of the super duplex bars at Lakshya Steel is produced using quality raw materials and modern processing. All bars are screened by stringent checks in order to eliminate flaws. Lakshya Steel is one of the trusted suppliers of super duplex bar, which supplies super duplex round bar, super duplex 2507 round bar, 2507 round bar and 2507 bar, super duplex round bar, super duplex 2507 round bar, UNS S32750 round bar, UNS S32760, 2507 round bar, and 2507 bar.

Frequently Asked Questions About Super Duplex Round Bar

Is super duplex better than 316?

Yes, super duplex is superior to 316 stainless steel with 3-4 times higher yield strength and approximately twice the pitting corrosion resistance. It offers better chloride stress corrosion cracking resistance at less than twice the cost.

What is the difference between SS and DSS?

Stainless steel (SS) typically refers to austenitic grades with single-phase structure, while duplex stainless steel (DSS) has a dual-phase microstructure containing 50% austenite and 50% ferrite, providing superior strength and corrosion resistance.

What is super duplex used for?

Super duplex is used in oil and gas, subsea equipment, chemical processing, marine applications, pollution control, pumps, valves, heat exchangers, acid handling, water treatment, and pulp/paper industries requiring high corrosion resistance.

Is 2205 duplex or super duplex?

The duplex stainless steel family offers a range of options, with S31803 (2205) and super duplex S32750 (2507) being popular choices. Both are strong and resist corrosion well, making them ideal for tough applications. Duplex 2205 offers a good balance of these features, while super duplex 2507 is even stronger and resists harsher environments even better.
