2507 super duplex stainless steel 2024-9-16

2507 (UNS S32750) Super Duplex Stainless Steel is an advanced high-performance alloy with exceptional properties, making it the first choice for a variety of applications. The following are the key features and benefits of 2507 Super Duplex Stainless Steel:

Corrosion resistance: 2507 has excellent resistance to general corrosion, pitting corrosion, crevice corrosion and stress corrosion cracking.
The high chromium (24-26%) and molybdenum (3-4%) content in 2507 provides excellent protection from corrosive environments including seawater, chlorides, acids and high temperature oxidation.
This exceptional corrosion resistance makes 2507 ideally suited for use in harsh corrosive environments such as offshore, coastal and industrial environments.

Mechanical Strength: 2507 Super Duplex Stainless Steel has extremely high tensile and yield strengths.
Typical tensile strengths range from 800 to 1000 MPa and yield strengths are typically 550 to 700 MPa.
The high strength-to-weight ratio of 2507 allows the design of lighter, more efficient structural components compared to traditional steel.

Toughness and Impact Resistance: 2507 exhibits excellent toughness and impact resistance even at low temperatures.
The balanced austenite-ferrite microstructure of 2507 helps it withstand impact and cyclic loading without compromising structural integrity.

Thermal and low temperature stability: 2507 super duplex stainless steel maintains its mechanical properties and corrosion resistance at both high and low temperatures.
This thermal stability and resistance to brittleness at low temperatures make 2507 suitable for applications in a variety of climate conditions, including liquefied natural gas (LNG) storage and transportation.

Solderability and Fabrication: 2507 is considered weldable, although it requires careful control of welding parameters to maintain the required ferrite-austenite balance and prevent the formation of harmful phases.
With proper welding techniques, 2507 can be easily fabricated into a variety of components and structures.

Main applications of 2507 super duplex stainless steel:

Offshore oil and gas platforms and subsea infrastructure
Chemical and Petrochemical Processing Equipment
Power generation components such as heat exchangers and turbines
Desalination and Water Treatment Plants
Cryogenic storage and transportation systems
Pulp and paper industry equipment

Building and structural applications in coastal or marine environments

The combination of exceptional corrosion resistance, high strength and thermal stability makes 2507 Super Duplex Stainless Steel a versatile, high-performance material suitable for applications requiring long-term durability, reliability and low maintenance costs in challenging environments.
