Product Overview

ASME SA789 UNS S32750 Super Duplex Stainless Steel Seamless Tube is a specification for seamless tubes made from UNS S32750, a super duplex stainless steel. This material is known for its exceptional combination of high strength, excellent corrosion resistance, and good toughness, making it suitable for demanding applications in harsh environments.

Key Features

High Strength: UNS S32750 has a higher yield strength compared to standard duplex and austenitic stainless steels, making it suitable for high-pressure applications.
Excellent Corrosion Resistance: Superior resistance to pitting, crevice corrosion, and stress corrosion cracking (SCC), especially in chloride-rich environments like seawater.
Balanced Microstructure: Dual-phase microstructure (approximately 50% austenite and 50% ferrite) contributes to its strength and corrosion resistance.
Good Weldability and Fabricability: Can be welded and fabricated using standard techniques with proper procedures.
Resistance to Acids and Chemicals: Performs well in environments with acids, alkalis, and other corrosive chemicals.

Technical Specifications

Material Composition:

Chromium (Cr): 24-26%
Molybdenum (Mo): 3-4%
Nickel (Ni): 6-8%
Nitrogen (N): 0.24-0.32%

Mechanical Properties:

Tensile Strength: ≥ 800 MPa (116 ksi)
Yield Strength: ≥ 550 MPa (80 ksi)
Elongation: ≥ 15%

Testing Requirements: Hydrostatic testing or non-destructive testing (NDT) to ensure integrity, with additional tests like pitting resistance testing (ASTM G48) as required.

Heat Treatment: Tubes are typically supplied in the solution-annealed condition to optimize corrosion resistance and mechanical properties.

Applications

Oil and Gas Industry: Offshore/onshore pipelines, downhole and subsea equipment
Chemical and Petrochemical Industry: Heat exchangers, condensers, process piping
Desalination Plants: Seawater desalination components
Power Generation: Nuclear/fossil fuel plants, FGD systems
Marine and Shipbuilding: Seawater cooling systems, propulsion components
Pulp and Paper Industry: Bleaching equipment
Pharmaceutical Industry: High-purity systems
Food and Beverage Industry: Sanitary processing equipment
Water Treatment: Wastewater treatment plants
Aerospace and Defense: High-strength components
