What are Tube Fittings Super Duplex?
Super Duplex Tube Fittings are exquisitely machined products made of super duplex stainless steel, a substance that incorporates the advantages of ferritic and austenitic microstructures. This is the alloy that is generally made of iron, chromium, nickel, and increased amounts of molybdenum, making it highly durable. Owing to this balanced make-up, Super Duplex Compression Fittings provide excellent resistance to localised corrosion, such as pitting or stress corrosion cracking, even in a challenging environment.
The Super Duplex Instrumentation Fittings are also tested to be reliable at moderate temperatures and tougher and better at corrosion performance than the conventional stainless-steel grades. Alloy 2507 Compression Tube Fittings are famous with respect to their high tensile strength and are widely applicable in industries requiring secure and leak-free connections at high pressure as well as operation in highly corrosive environments.

FAQ’s About Super Duplex Tube Fittings
What is meant by “Super Duplex” in Super Duplex Tube Fittings?
Super Duplex refers to a high-performance stainless steel alloy typically S32750 / S32760 (also known as Super Duplex 2507) that combines both ferritic and austenitic microstructures. This gives it superior strength, toughness, and corrosion resistance compared to standard stainless-steel grades.
How do I ensure I’m getting genuine Super Duplex fittings (S32750 / S32760)?
Always verify that the material grade is listed clearly (e.g., S32750 or S32760 / UNS 1.4410 or 1.4501), and that the supplier adheres to recognized standards (ASTM/ASME). Request material test certificates (MTC), and check dimensions and specifications match standard size/pressure ratings for compression or instrumentation fittings.
Can Super Duplex Tube Fittings be used for both hydraulic and instrumentation applications?
Yes. Super Duplex fittings are widely used for both instrumentation tubing (for process control, chemical feeds, instrumentation lines) and hydraulic lines, especially in environments requiring high strength, corrosion resistance, and leak-free connections.
