Product Description

Product Description

ASTM A790 UNS S32750 Super Duplex Stainless Steel

ASTM A790 is the standard specification for seamless and welded ferritic/austenitic stainless steel pipes. UNS S32750, commonly known as Super Duplex 2507, is a super duplex stainless steel designed for applications that demand exceptional strength and corrosion resistance.

Chemical Composition:

• Carbon (C): ≤ 0.03%
• Manganese (Mn): ≤ 1.20%
• Phosphorus (P): ≤ 0.035%
• Sulfur (S): ≤ 0.020%
• Silicon (Si): ≤ 0.80%
• Chromium (Cr): 24.0-26.0%
• Nickel (Ni): 6.0-8.0%
• Molybdenum (Mo): 3.0-5.0%
• Nitrogen (N): 0.24-0.32%
• Iron (Fe): Balance

Key Features:

1. High Strength: UNS S32750 has twice the yield strength of standard austenitic stainless steels, making it suitable for high-pressure applications.
2. Corrosion Resistance: Exceptional resistance to pitting, crevice corrosion, and chloride stress corrosion cracking. Ideal for environments with aggressive chemicals and saline conditions.
3. Good Weldability: Despite its high strength, it maintains good weldability, which is important for construction and fabrication.
4. Excellent Toughness: Maintains high toughness and ductility at both high and low temperatures.

Applications:

• Oil and Gas Industry: Used in offshore oil rigs, pipelines, and equipment that require high strength and resistance to corrosion.
• Chemical Processing: Suitable for chemical processing plants where resistance to corrosive substances is critical.
• Desalination Plants: Used in desalination plants due to its high resistance to saline environments.
• Marine Applications: Ideal for marine environments, including shipbuilding and coastal infrastructure.
• Heat Exchangers: Employed in heat exchangers and condensers where high-pressure resistance and corrosion resistance are needed.

Summary:

ASTM A790 UNS S32750 (Super Duplex 2507) is a high-performance stainless steel known for its excellent combination of strength and corrosion resistance. This material is ideal for demanding applications in the oil and gas, chemical processing, desalination, and marine industries. Its high yield strength and superior resistance to chloride-induced stress corrosion cracking make it a reliable choice for high-pressure and corrosive environments.
