What are Duplex Steel S31803 Flanges?
Duplex Steel S31803 Flanges are high-quality flange fittings made from Duplex Stainless Steel Grade S31803. This grade combines ferritic and austenitic stainless steels, giving these flanges outstanding corrosion resistance and high strength. S31803 Flanges are widely used in industries like oil and gas, chemical processing, and offshore installations, where they provide excellent durability and performance under harsh conditions.
What is Duplex Steel S32205 Flange Used For?
Duplex Steel S32205 Flange is a specialized flange designed for high-corrosion-resistance applications. Made from Duplex Stainless Steel Grade S32205, these flanges are ideal for environments with high chloride exposure, such as seawater applications, desalination plants, and chemical processing facilities. The S32205 Flange offers superior protection against pitting and crevice corrosion, making it a reliable choice for demanding environments.
What are the Advantages of Duplex Steel 2205 Flanges?
Duplex Steel 2205 Flanges offer several notable advantages due to their unique properties
- Superior Corrosion Resistance: Excellent resistance to chloride-induced corrosion, ideal for harsh environments.
- High Strength: Duplex Steel 2205 Flanges are about twice as strong as standard austenitic steels, making them suitable for high-pressure applications.
- Excellent Toughness: These flanges maintain good toughness and can withstand extreme temperatures and pressures.
- Good Weldability & Formability: Easy to work with during installation, allowing for efficient and effective fabrication.
- Cost-Effective: Lower nickel and molybdenum content reduces costs compared to other high-alloy stainless steels.
These properties make Duplex Steel 2205 Flanges a great choice for demanding applications, offering reliable and long-lasting performance.

FAQs
What is a duplex flange?
Duplex flanges are high-strength, corrosion-resistant components made from duplex stainless steel. They offer superior durability and strength compared to standard stainless steel flanges, making them ideal for demanding applications in industries like chemical processing, marine, and oil & gas.
What is a duplex stainless steel flange?
Duplex stainless steel flanges are made from a blend of austenitic and ferritic stainless steels, offering high stress corrosion cracking resistance. Grades like 2205, F51, F53, and F60 provide superior strength and corrosion resistance compared to standard 304 and 316 stainless steels.
What material is used in super duplex flanges?
Super Duplex Flanges are made from a high-performance alloy containing 25% chromium, 4% molybdenum, and 7% nickel. This composition offers exceptional strength, corrosion resistance, and durability for demanding applications in industries such as oil & gas and chemical processing.
