All our products are sourced from reputed manufacturers, who specialize in developing the entire range as per the application needs of our clients. Our vendors make use of high-grade raw material and sophisticated methodologies for manufacturing these Super Duplex products.

We hold stock of Super Duplex stainless steel plate specifications UNS S32750 (1.4410) and UNS S32760 (1.4501). In order to get more specific information on these steel grades click the following links:

Super Duplex S32750
Super Duplex S32760
A Super Duplex stainless steel is a type of Duplex stainless steel with enhanced corrosion resistance which is categorised by its PREN being greater than 40. A standard Duplex like the S31803 grade stocked by us has a PREN of around 35. The Pitting Resistance Equivalent Number (PREN) is widely used as a means of comparing the relative corrosion resistance of different steel grades. The PREN is obtained by applying a mathematical formula to the chemical composition of a steel so that PREN = %Cr (3.3 x %Mo) (16 x %N).

As a part of the Duplex family of stainless steels Super Duplex stainless has a microstructure which is split roughly 50:50 between austenite and ferrite. It differs from Duplex in its chemical composition (with increased amounts of Molybdenum, Nickel, and Chromium) and its mechanical properties (higher proof stress and tensile strength). This highly alloyed product is especially designed for marine, chemical, and oil engineering applications requiring both high mechanical strength and resistance to corrosion in extremely aggressive environments (chloride-containing acids etc.).

Super Duplex stainless steel, relative to other stainless steel products, gives

High corrosion resistance
High resistance to stress corrosion cracking
High yield strength and tensile strength
It is used extensively for offshore oil and gas applications and can be found in flow lines, risers, process vessels, separators, coolers, manifolds, and process piping. Onshore it can be found in heat exchangers, boilers, and pressure vessels in petrochemical and chemical processing plant.

S32760 (1.4501) Super Duplex Steel Sheet

Super Duplex UNS S32760 | 1.4501

We stocks super duplex stainless steel plates which are certified to material grades UNS S32760 and 1.4501. The steels are also compatible with the branded Zeron 100 designation. E562 microstructure analysis, and corrosion testing to G48 or A293 Method C. In order to further ensure good corrosion resistance. All material is produced and certified in accordance with NORSOK MDS D55 with plates up to and including 35 mm thick certified to Revision 4. Mill test certificates are produced with third party inspection to EN 10204 UNS S32760 Properties Chemical Analysis (% max or range)
