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. The ASME SA789 standard specifies the requirements for seamless and welded stainless steel tubes used in general service and corrosive 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: Offers superior resistance to pitting, crevice corrosion, and stress corrosion cracking (SCC), especially in chloride-rich environments like seawater.
  • Balanced Microstructure: The material has a dual-phase microstructure (approximately 50% austenite and 50% ferrite), which contributes to its strength and corrosion resistance.
  • Good Weldability and Fabricability: UNS S32750 can be welded and fabricated using standard techniques, though proper procedures must be followed to maintain its properties.
  • Resistance to Acids and Chemicals: Performs well in environments with acids, alkalis, and other corrosive chemicals.
ASME SA789 Specification Details
Material Composition:

UNS S32750 has a specific chemical composition, including high levels of chromium (Cr), molybdenum (Mo), and nitrogen (N):

  • 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%
Additional Requirements:
  • Dimensional Tolerances: Specified for outer diameter, wall thickness, and length
  • Testing Requirements: Hydrostatic testing or non-destructive testing (NDT) required
  • Heat Treatment: Typically supplied in solution-annealed condition
