Duplex Steel UNS S32760 Flanges Price Chart

Duplex Steel UNS S32760, also known as Super Duplex F55 or Zeron 100, as a premium material engineered for extreme environments.

As a manufacturer, we provide this price chart and technical guide to help procurement professionals.

Understanding UNS S32760

The term "Super Duplex" isn't marketing jargon; it is a technical classification for duplex stainless steels with a Pitting Resistance Equivalent Number (PREN) greater than 40.

The 50/50 austenitic-ferritic microstructure provides the "best of both worlds": the stress corrosion cracking resistance of ferritic steel and the ease of fabrication of austenitic steel.

Mechanical Properties

Because its yield strength is nearly double that of 316L stainless steel, you can design systems with thinner sections without sacrificing safety.

Tensile Strength (min): 750 MPa (109 ksi)

Yield Strength (0.2% Offset, min): 550 MPa (80 ksi)

Elongation (min): 25%

Hardness (max): 270 HBW (28 HRC)

Duplex Steel UNS S32760 Flanges Price Chart

The table below provides estimated price ranges for common UNS S32760 flange types. Please note that these are market reference prices based on standard dimensions (2" to 12") and pressure classes (150# to 600#).

Actual pricing fluctuates based on alloy surcharges, specific dimensional requirements, and order volume.

For larger sizes (26"+) under ASME B16.47 Series B, contact us for quotes. Volume orders receive up to 15% off, with expedited delivery options.

Factors Influencing the Price of S32760 Flanges

1. Raw Material Volatility

UNS S32760 is heavily alloyed with molybdenum and nickel. The global market prices for these elements fluctuate daily, directly impacting the base cost of the raw billet . A "too good to be true" price often indicates a lack of traceability or incorrect chemistry.

2. Manufacturing Process & Certification

Producing a sound super duplex flange requires precise control. Our process involves:

Forging: Starting with certified billet, we forge the flange to refine the grain structure.

Solution Annealing: After forging, the flanges undergo a critical solution heat treatment and rapid quenching to achieve the correct 50/50 austenite-ferrite phase balance. Improper heat treatment destroys corrosion resistance.

Traceability: Each piece is stamped and tracked. We offer EN 10204 3.1 or 3.2 certification, which guarantees material and mechanical property verification . This level of assurance adds to the cost but eliminates the risk of field failure.

3. Dimensional Standards and Testing

Compliance with ASME B16.5 requires precise machining. Furthermore, for critical service, we conduct Positive Material Identification (PMI), Hydrostatic testing, and Ultrasonic examination.

A flange from a non-certified source may skip these steps, offering a lower price but presenting a significant operational risk.

4. Flange Type and Pressure Class

Weld Neck Flanges: Higher price due to the forged "hub" and the precision machining required for the weld end.

RTJ (Ring Type Joint): These require an additional precision-machined groove, adding 10–15% to the cost of a standard Raised Face (RF) flange.

Common Flange Types and Specifications

We offer a wide array of Duplex Steel UNS S32760 flange types to suit diverse piping needs, all manufactured to ASME B16.5 (1/2"-24") and B16.47 (26"-60") standards.

Weld Neck (WN) flanges provide robust reinforcement for high-pressure systems, featuring a tapered hub for seamless welding.

Slip-On (SO) flanges are cost-effective for low-pressure applications, sliding over pipes for easy alignment.

Blind (BL) flanges seal vessel openings, ideal for testing or isolation.

Socket Weld (SW) and Threaded (THD) types suit smaller diameters, offering strong joints without welding prep.

Lap Joint (LJ) flanges allow for easy disassembly, while Orifice flanges facilitate flow measurement.

Pressure classes range from 150 to 2500, with facings including Raised Face (RF), Flat Face (FF), and Ring Type Joint (RTJ) for optimal sealing.

Our flanges comply with ASTM A182 F55, NORSOK MDS D51-D58, and NACE MR0103, ensuring compatibility with UNS S32760 pipes.
