Product Details

2205 ASTM A789 UNS S31803 Duplex Stainless Steel Seamless Tube

Duplex S31803 is also known as UNS S32205, referring to its composition of approximately 22% chromium, 5% nickel, 3% molybdenum, and 2% nitrogen. A789 S31803 tubes are classified as "duplex" stainless steel, which means they have a two-phase microstructure consisting of both austenite and ferrite. This dual-phase structure provides a combination of high strength and excellent corrosion resistance, making it suitable for demanding applications.

Here are some of the key advantages of using duplex S31803 tubes:

Corrosion Resistance: Duplex S31803 tubes exhibit excellent resistance to corrosion in various environments, including chloride-containing and acidic environments, making them suitable for harsh industrial applications.
High Strength: These tubes have higher strength compared to austenitic stainless steels, allowing for thinner wall thicknesses and lighter weight designs while maintaining structural integrity.
Good Toughness: Duplex S31803 tubes offer good toughness, making them suitable for applications where impact resistance is important.
Good Weldability: They have good weldability characteristics, which simplifies the fabrication process and reduces the risk of welding defects.
High Temperature Resistance: Duplex S31803 tubes can withstand high temperatures, making them suitable for applications in elevated temperature environments.
Cost-Effective: Despite their superior properties, duplex S31803 tubes are relatively cost-effective compared to other high-performance materials.
Low Thermal Expansion: These tubes have low thermal expansion coefficients, which helps reduce the risk of thermal distortion in applications involving temperature fluctuations.
Erosion Resistance: Duplex S31803 tubes offer good resistance to erosion and erosion-corrosion, making them suitable for applications where abrasive substances are present.
