Product Description

ASTM A789 S32750 Super Duplex Stainless Steel Seamless Tube

ASTM A789 S32750 is a high-performance super duplex stainless steel that offers exceptional strength, corrosion resistance, and durability. It is widely utilized in industries that demand high reliability and performance under challenging conditions, such as oil and gas, chemical processing, and marine applications.

Key Features

Super Duplex Composition:
- Contains a balanced mix of austenitic and ferritic stainless steel microstructures, offering superior mechanical properties and corrosion resistance compared to standard duplex grades.
- Typical composition includes high levels of chromium (24-26%), molybdenum (3-5%), and nitrogen, providing excellent resistance to pitting and crevice corrosion.
Corrosion Resistance:
- Excellent resistance to chloride-induced stress corrosion cracking (SCC), pitting, and crevice corrosion, especially in seawater and high-chloride environments.
- Superior to 316L and 317L stainless steels in harsh environments.
High Strength:
- Yield strength is approximately twice that of conventional austenitic stainless steels.
- Ensures durability under high pressure and temperature conditions.
Seamless Construction:
- Manufactured without welding, providing uniform strength and reducing the risk of defects or leaks.
- Ideal for critical applications requiring high integrity and reliability.

Specifications

Standard: ASTM A789
Grade: UNS S32750 (commonly referred to as SAF 2507)
Dimensions: Available in a range of sizes, typically conforming to customer-specific requirements.
Manufacturing Process: Seamless cold-drawn or hot-extruded tubes.

Applications

Oil & Gas Industry:
- Used in offshore platforms, subsea pipelines, and heat exchangers.
Chemical Processing:
- Ideal for handling aggressive chemicals, acids, and high-chloride solutions.
Desalination Plants:
- Suitable for seawater handling and brine systems.
Marine Industry:
- Used in shipbuilding, ballast systems, and seawater cooling systems.
