Super Duplex S32760 Pipes & Tubes

When it comes to handling extreme conditions in marine, chemical, and oil & gas industries, Super Duplex S32760 Pipes & Tubes are the go-to choice. These high-performance materials offer superior strength, corrosion resistance, and longevity—making them ideal for the most demanding applications.
In this blog, we'll dive into what makes Super Duplex S32760 so special, its key features, applications, and why it stands out among other stainless steel alloys.
What is Super Duplex S32760?
Super Duplex S32760, also known as Zeron® 100, is a super duplex stainless steel alloy containing high levels of chromium, molybdenum, and nitrogen. Its balanced dual-phase structure (austenite and ferrite) gives it outstanding mechanical strength and corrosion resistance—especially in aggressive environments like seawater or acidic industrial processes.
Chemical Composition (%):
Chromium (Cr): ~24-26%
Nickel (Ni): ~6-8%
Molybdenum (Mo): ~3-4%
Nitrogen (N): ~0.2-0.3%
Iron (Fe): Balance
This composition significantly enhances its pitting resistance, stress corrosion ...
... cracking resistance, and overall durability.
Key Features of S32760 Pipes & Tubes
Exceptional Corrosion Resistance
Outstanding performance in chloride-rich environments (e.g., seawater)
Excellent resistance to crevice, pitting, and general corrosion
High Mechanical Strength
Yield strength almost twice that of austenitic stainless steels (like 316L)
Good Weldability and Formability
Can be welded using standard methods with proper procedures
Suitable for forming, bending, and machining
Cost-Effective Over Time
Reduced maintenance and longer service life offset higher initial costs
Common Applications
Due to its robustness, Super Duplex S32760 pipes and tubes are widely used in:
Oil & Gas Exploration and Processing
Subsea pipelines, risers, and manifolds
Desalination Plants
Heat exchangers, evaporators, and high-pressure piping
Chemical and Petrochemical Industries
Reactors, pressure vessels, and heat exchangers
Marine and Offshore Engineering
Structural components exposed to saltwater
Pulp & Paper Industry
Digesters and bleaching equipment
