Product Overview

The ASTM A789 S32750 Duplex Steel Seamless Tube is manufactured from S32750 duplex stainless steel, which combines both austenitic and ferritic properties to offer superior corrosion resistance, strength, and toughness. This tube is designed for heat exchanger systems, particularly in aggressive environments such as seawater, chemical processing, and petrochemical industries. Duplex steel ensures long-lasting performance in high-pressure, high-temperature applications, providing excellent resistance to stress corrosion cracking (SCC) and pitting corrosion.

Chemical Composition - ASTM A789 S32750 Duplex Steel
Element Content (%)
C ≤ 0.03
Mn 1.00 - 2.00
Si 0.80 - 1.20
P ≤ 0.035
S ≤ 0.015
Cr 24.0 - 26.0
Ni 6.0 - 8.0
Mo 3.0 - 5.0
N 0.24 - 0.32
Fe Balance
Mechanical Properties - S32750 Duplex Steel
Property Value
Tensile Strength ≥ 550 MPa
Yield Strength ≥ 450 MPa
Elongation ≥ 25%
Hardness ≤ 250 HB
Impact Toughness Excellent, even at low temp.
Maximum Operating Temp 300°C (572°F)
Advantages
  • Superior Corrosion Resistance
    Excellent resistance to pitting, crevice corrosion, and stress corrosion cracking (SCC), especially in chloride-rich environments.
  • High Strength and Durability
    Offers higher tensile strength than traditional austenitic stainless steels, with better performance in high-pressure systems.
  • Cost-Effective for Aggressive Environments
    The combination of austenitic and ferritic phases makes this duplex steel a more affordable solution for harsh applications compared to fully austenitic alloys.
  • Outstanding Heat Transfer Efficiency
    The tube design ensures optimal fluid flow and heat transfer, essential for efficient operation in heat exchanger applications.
  • Long Service Life
    Superior resistance to corrosion fatigue and mechanical wear ensures long-term performance in extreme conditions.
Applications

This tube is used extensively in the following heat exchanger applications:

  • Seawater Heat Exchangers
    Ideal for marine environments or applications exposed to seawater.
  • Petrochemical Industry
    Used in cooling systems and heat exchangers where aggressive chemical processes are involved.
  • Power Plants
    Effective for HRSG systems and economizers in both fossil fuel and nuclear plants.
  • Chemical Processing Units
    Effective in high-pressure chemical reactors and heat exchanger systems dealing with corrosive materials.
