Product Description

ASTM A789 S32750 Super Duplex Stainless Steel Seamless Tube For Heat Exchanger

Description:

This seamless tube is made from ASTM A789 S32750 Super Duplex Stainless Steel, designed for high-strength, corrosion-resistant heat exchanger applications. It combines the properties of austenitic and ferritic stainless steels, offering excellent resistance to chloride stress corrosion cracking, pitting, and crevice corrosion, especially in marine and chemical process environments.

Chemical Composition (S32750):

Element	Content (%)
Chromium (Cr)	24.0 – 26.0
Nickel (Ni)	6.0 – 8.0
Molybdenum (Mo)	3.0 – 5.0
Nitrogen (N)	0.24 – 0.32
Manganese (Mn)	≤ 1.2
Carbon (C)	≤ 0.030
Silicon (Si)	≤ 0.80
Phosphorus (P)	≤ 0.035
Sulfur (S)	≤ 0.020
Iron (Fe)	Balance

Mechanical Properties:

Property	Typical Value
Tensile Strength	≥ 795 MPa
Yield Strength (0.2%)	≥ 550 MPa
Elongation	≥ 15%
Hardness (HRB)	≤ 100

Advantages:

Superior Corrosion Resistance: Excellent in brine, seawater, and aggressive chemical media.
High Strength: Double the yield strength of austenitic stainless steels (e.g., 316L).
Stress Corrosion Resistance: Especially effective against chloride-induced cracking.
Long Service Life: Ideal for harsh and corrosive operating environments.
Low Thermal Expansion: Reduces stress during temperature fluctuations in heat exchangers.

Applications:

Heat Exchangers in:
- Desalination plants
- Offshore oil & gas platforms
- Marine cooling systems
- Chemical and petrochemical processing
Condenser and evaporator tubes
Seawater systems in refineries and power stations
High-pressure and high-temperature environment
