Description

Duplex Stainless Steel Tube ASME SA789 S32750 For Heat Exchanger Application​

The Duplex Stainless Steel ASME SA789 S32750 heat exchanger tube is a duplex stainless steel tube known for its excellent corrosion resistance, particularly in harsh environments. It features a balanced microstructure of austenite and ferrite, providing high strength and toughness. Typically, it has a minimum yield strength of 450 MPa and offers good resistance to pitting and crevice corrosion. This tube is commonly used in oil and gas, chemical processing, and seawater applications due to its ability to withstand high pressures and temperatures. Additionally, it meets stringent ASME standards, ensuring reliability and safety in heat transfer applications.

Mechanical Properties:

Grade Tensile Strength Yield Strength Elongation Hardness
S32750 ≥ 550 MPa (80 ksi) ≥ 750 MPa (109 ksi) ≥ 15% in 50 mm Typically ≤ 32 HRC

Key Features:

  • Material Composition:S32750 Stainless Steel: Super duplex alloy with high chromium (24-26%), molybdenum (3-5%), and nitrogen.
  • Corrosion Resistance: Excellent resistance to pitting, crevice corrosion, and chloride stress corrosion cracking.
  • High Strength: Greater mechanical strength than standard austenitic stainless steels.
  • Durability: Maintains structural integrity under high pressure and temperature.

Application:​

  1. Heat Exchangers: Widely used in shell-and-tube heat exchangers, especially in oil refineries, petrochemical plants, and power generation.
  2. Seawater Applications: Suitable for cooling systems in marine environments due to its excellent resistance to seawater corrosion.
  3. Chemical Processing: Used in heat exchangers that handle aggressive chemicals and high temperatures.
