What is Super Duplex Steel S32750 Round Bar?
Super Duplex Steel S32750 Round Bar is a high-alloy stainless steel that combines the best properties of austenitic and ferritic steels. This dual-phase structure gives it superior strength and excellent corrosion resistance, making it ideal for use in harsh environments. The material is often referred to by its UNS designation, UNS S32750, and is widely used in industries such as oil and gas, chemical processing, marine, and desalination.
Key Properties of Super Duplex Steel S32750 Round Bar
High Strength and Toughness
One of the most notable properties of Super Duplex Steel S32750 Round Bar is its high strength. The material has a tensile strength that is almost double that of standard austenitic stainless steels. This makes it an excellent choice for applications where mechanical strength is critical, such as in offshore oil rigs and subsea equipment.
Tensile Strength: 800-1000 MPa
Yield Strength: 550 MPa
Exceptional Corrosion Resistance
Super Duplex S32750 Round Bar offers outstanding resistance to a wide range of corrosive environments, including those containing chlorides, acids, and other aggressive chemicals. This makes it particularly suitable for use in chemical processing plants, seawater desalination units, and marine applications.
Pitting Resistance Equivalent (PRE): >40
Stress Corrosion Cracking Resistance: Excellent
Excellent Weldability
Despite its high alloy content, Super Duplex UNS S32750 Bars exhibit excellent weldability. This allows for the fabrication of complex structures and components without compromising the material’s integrity. Proper welding techniques and post-weld heat treatment can further enhance the material’s performance.
Good Fatigue Resistance
The fatigue resistance of Super Duplex Steel S32750 Round Bar is another key property that makes it suitable for high-performance industries. The material can withstand cyclic loading and stress, which is crucial for applications such as rotating machinery and structural components in offshore platforms.
Thermal Conductivity and Expansion
Super Duplex S32750 Round Bar has a lower thermal expansion coefficient compared to austenitic stainless steels. This property, combined with good thermal conductivity, makes it an excellent choice for applications involving thermal cycling and high-temperature environments.
Thermal Expansion Coefficient: 13.0 x 10^-6 /K
Thermal Conductivity: 15 W/m.K
Magnetic Properties
Unlike austenitic stainless steels, Super Duplex Steel S32750 Round Bar exhibits magnetic properties due to its ferritic phase. This can be advantageous in certain applications where magnetic properties are required.
