Duplex Steel Round Bars Supplier – ASTM A276 / A479 Grades
Choosing the right material is critical when your project operates under pressure, corrosion, or extreme mechanical stress. Duplex steel round bars are designed exactly for such demanding conditions. At Zeon Exports, we supply high-quality duplex steel round bars that meet ASTM A276 and ASTM A479 standards, trusted by industries worldwide.
What Are Duplex Steel Round Bars?
Duplex steel is a combination of two stainless steel structures – austenitic and ferritic. This dual structure gives duplex steel round bars higher strength, excellent corrosion resistance, and longer service life compared to conventional stainless steels.
Round bars manufactured from duplex steel are widely used in machining, fabrication, and structural applications. They offer a perfect balance of toughness and workability, making them suitable for critical components where failure is not an option.
As an experienced Duplex Steel Round Bars Supplier – ASTM A276 / A479 Grades, Zeon Exports ensures consistent quality across every supplied bar.

Understanding standards helps buyers select the correct product:
- ASTM A276 Duplex Steel Round Bars
Used mainly for general engineering and structural purposes. These bars are available in hot-finished and cold-finished conditions and are known for good surface finish and dimensional accuracy. - ASTM A479 Duplex Steel Round Bars
Designed for pressure vessels, valves, fittings, and high-performance components. This standard demands tighter tolerances and enhanced mechanical properties.
Zeon Exports stocks and supplies both standards, allowing buyers to source everything from one reliable Duplex Steel Round Bars Supplier – ASTM A276 / A479 Grades.
