Duplex Steel Round Bars Supplier

Duplex steel round bars are a type of steel bar that is made from duplex stainless steel. Duplex stainless steel is a family of stainless steels that consists of a combination of austenite and ferrite phases in roughly equal proportions. This unique microstructure provides a balance of mechanical properties, including high strength and excellent corrosion resistance.

For top-quality round bars that offer corrosion resistance and high performance, rely on us as your trusted Duplex Steel Round Bars Supplier.

As an established Duplex Steel Round Bars Manufacturer, we specialize in crafting high-quality round bars from Duplex steel, ensuring exceptional durability and structural integrity for various critical applications in industries like marine and chemical processing

Common grades of duplex stainless steel used for round bars include SAF 2205 (UNS S31803/S32205) and SAF 2507 (UNS S32750). These grades offer a balance of properties and are widely available in the market.

Duplex steel round bars are commonly used in various industries, such as oil and gas, chemical processing, marine, and construction. They are particularly suitable for applications where a combination of strength, corrosion resistance, and toughness is required.

Duplex stainless steels offer excellent resistance to various corrosive environments, including chloride-induced stress corrosion cracking, pitting, and crevice corrosion. This makes them suitable for use in aggressive environments. Duplex steel round bars have higher strength compared to austenitic stainless steel. This enables their use in structural applications where strength is a critical factor. Duplex stainless steels exhibit good toughness, allowing them to withstand impact and heavy loads without undergoing brittle fracture. This makes them suitable for applications subjected to dynamic and heavy-duty conditions.

Duplex steel round bars can be readily welded using conventional welding techniques. However, it is essential to use suitable filler materials and follow proper welding procedures to maintain the desired properties of the material. Duplex stainless steels maintain their mechanical properties and corrosion resistance at elevated temperatures, making them suitable for applications in high-temperature environments.

What is a Duplex Steel Round Bar?

Duplex Steel Round Bar is a solid cylindrical bar made from Duplex stainless steel. Duplex stainless steel is a corrosion-resistant alloy that combines the benefits of austenitic & ferritic stainless steel. The Round Bar shape allows for versatile use in various applications.

Can Duplex Steel Round Bars be machined or forged?

Yes, Duplex Steel Round Bars can be machined and forged. Duplex stainless steel is known for its good machinability and enforceability, allowing for various fabrication processes. It is important to use appropriate machining and forging techniques specific to Duplex stainless steel to ensure the best results and maintain its mechanical properties.

Are Duplex Steel Round Bars available in different sizes and lengths?

Yes, Duplex Steel Round Bars are available in various sizes and lengths to accommodate application requirements. They are manufactured in standard sizes & lengths, conforming to industry standards, but can also be custom-cut to specific lengths if needed. It is important to select the appropriate size and length of the Round Bar to meet the requirements of the intended application.
