About Stainless Steel Super Duplex Flanges

Super Duplex Stainless Steel Flanges connect piping, offering superior strength and corrosion resistance (especially to chlorides) due to their unique alloy (approx. 25% Cr, 4% Mo, 7% Ni), making them ideal for harsh oil/gas, marine, and chemical environments where standard stainless steels fail, available in various types (Weld Neck, Blind, Slip-On) for high-pressure, corrosive applications.

Key Characteristics

Composition: Contains high levels of Chromium (Cr), Molybdenum (Mo), and Nickel (Ni) (e.g., UNS S32750/2507).
Corrosion Resistance: Excellent resistance to pitting, crevice corrosion, and chloride stress corrosion cracking (SCC).
Mechanical Strength: High tensile and yield strength, combining properties of austenitic and ferritic steels.
High Performance: Withstands high temperatures and corrosive media better than standard duplex steels.

Common Applications

Oil & Gas: Offshore platforms, subsea equipment, pipelines.
Marine: Propellers, shafts, seawater systems.
Chemical Processing: Equipment, tanks, piping.
Power Generation: Flue gas desulfurization, heat exchangers.
Pulp & Paper: Bleaching equipment.

Types & Features

Types: Available as Weld Neck (WNRF), Blind, Slip-On (SORF), Socket Weld, Lap Joint, Threaded, etc..
Sealing: Used with gaskets (like Flat Face, Raised Face, Tongue & Groove) for a tight seal when bolted together.
Limitations: Can become brittle if held at temperatures above 300C (570F) for extended periods, requiring careful heat treatment.
