A789 S32750 Super Duplex Heat Exchanger Tube, Seamless And Solution Annealed, Eddy Current Test / Hydrostatic Tested

 

 

Overview

 

ASTM A789 S32750 (2507/1.4410) is a premium super duplex stainless steel seamless tube engineered specifically for heat exchangers, condensers and evaporators.

 

With a balanced 50% austenite and 50% ferrite microstructure, it features high mechanical strength, excellent chloride pitting, crevice and stress corrosion resistance, and superior thermal conductivity.

 

It is widely used in seawater desalination, offshore oil & gas, petrochemical, power plant and FGD systems for high-pressure, high-temperature and harsh corrosive working conditions.

 

 

Key Performance Features

  1. Double yield strength compared to 304/316L

  2. Outstanding resistance to chloride pitting, crevice corrosion & stress corrosion cracking

  3. Good thermal conductivity, higher than austenitic stainless steel

  4. Excellent erosion corrosion & fatigue resistance

  5. Suitable for high pressure & high temperature severe service

 

 

Mechanical Properties (Solution Annealed Condition)

  • Tensile Strength: ≥790 MPa

  • Yield Strength (0.2% Proof): ≥550 MPa

  • Elongation: ≥15%

  • Hardness: ≤310 HB / ≤32 HRC

  • Microstructure: Balanced 50% Ferrite + 50% Austenite

 

 

Manufacturing & Heat Treatment

  • Process: Seamless → Hot piercing → Cold drawn / Cold rolled

  • Heat Treatment: Solution annealing at 1020–1100°C, water quenched

  • Delivery Condition: Annealed, pickled & passivated, bright annealed optional

 

 

Available Size Range

  • Outer Diameter: 6.0mm – 114.3mm

  • Wall Thickness: 1.0mm – 8.0mm

  • Standard Length: 6000mm / 12000mm

  • Custom: U-bend heat exchanger tubes available

  • Tolerance: Strict OD & WT tolerance per ASTM A789
