Duplex Stainless Steel ASTM A789 S32205 Heat Exchanger Tube

Duplex Stainless Steel ASTM A789 S32205 Heat Exchanger Tube

Grade S32205 is a duplex stainless steel characterized by a roughly equal mixture of austenite and ferrite phases. This microstructure grants it superior strength and excellent resistance to stress corrosion cracking, pitting, and crevice corrosion compared to standard austenitic stainless steels. S32205 offering improved corrosion resistance and mechanical properties.

Chemical Composition:

Mechanical Properties:

Key Features:

• High Strength: Approximately twice the yield strength of austenitic stainless steels.
• Corrosion Resistance: Excellent resistance to pitting, crevice corrosion, and stress corrosion cracking, especially in chloride environments.
• Weldability: Good weldability with proper technique and post-weld treatment.
• Durability: High mechanical strength and toughness, even at low temperatures.

Applications:

1. Power Generation

• Condenser Tubes: Used in power plant condensers for efficient heat transfer and resistance to corrosion.
• Heat Recovery Systems: Suitable for heat recovery systems that require durable and corrosion-resistant tubing.
• Nuclear Power Plants: Ideal for nuclear power plant components exposed to aggressive cooling waters.

2. Pulp and Paper Industry

• Bleaching Equipment: Used in bleaching equipment due to its resistance to corrosive chemicals.
• Digesters and Pulp Washers: Suitable for digesters and pulp washers where high strength and corrosion resistance are required.
• Black Liquor Tanks: Ideal for black liquor tanks and other storage containers exposed to aggressive chemicals.

3. Pharmaceutical Industry

• Processing Lines: Used in pharmaceutical processing lines that handle corrosive substances at various temperatures.
• Sterilization Equipment: Suitable for sterilization equipment due to its excellent resistance to corrosive, high-temperature environments.
