Duplex Stainless Steel Bar

Duplex Stainless Steel Bar

Duplex stainless steel rods are high-performance metal products known for their unique corrosion resistance and high mechanical strength. These rods consist of a microstructure consisting of austenite and ferrite phases in approximately equal proportions. The dual construction contributes to its excellent resistance to a variety of corrosive environments, including chloride-induced stress corrosion cracking and pitting. Additionally, duplex stainless steel rods offer superior strength, allowing them to withstand heavy loads and high pressures. This makes them ideal for critical applications in industries such as oil and gas, chemical processing and offshore engineering.

What‘s The Feature Of Duplex Steel Rod?

Duplex Stainless Steel Rod exhibits excellent corrosion resistance, surpassing that of austenitic and ferritic stainless steel rods. It offers exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking, making it highly suitable for aggressive environments such as seawater, chloride-rich solutions, and acidic conditions.

Duplex Stainless Steel Rod provides higher strength compared to austenitic stainless steel rods. It has a higher yield strength, allowing for reduced rod diameters and weight savings in structural applications. This strength enables it to withstand heavy loads and mechanical stress.

Duplex Stainless Steel Rod maintains good toughness and ductility, ensuring resistance to impact and vibration. It can withstand dynamic loading and harsh working conditions without compromising its structural integrity.

Duplex Stainless Steel Rod is versatile and finds applications in various industries. It is commonly used in oil and gas, chemical processing, pulp and paper, desalination, and more. Its combination of corrosion resistance, strength, and toughness makes it suitable for critical applications such as shafts, fasteners, and structural components.

Duplex Stainless Steel Rod exhibits good weldability, allowing for efficient fabrication and installation. It can be easily welded using common welding techniques, although proper welding procedures should be followed to maintain its corrosion resistance and mechanical properties.

Duplex Stainless Steel Rod offers good heat resistance, allowing it to maintain its mechanical properties at elevated temperatures. It can withstand thermal cycling and is suitable for applications requiring resistance to high-temperature environments.
