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
