Ragavendra Engineering holds an extensive stock of Super Duplex stainless steel plate and is one of the few companies to keep both S32750 (1.4410) and S32760 (1.4501) material grades. All stock plate is manufactured by Western European steel makers, third party inspected, and certified in accordance with EN 10204 3.2. All plates are also certified in accordance with NORSOK MDS D55 and any plates up to an including 35 mm thick will be to NORSOK MDS D55 Revision 4.

Plates are stocked as large format (up to 12,000 mm long and 2,500 mm wide) which is designed to minimise fabrication costs for our customers by reducing the amount of welding required. The large format also gives us the opportunity to make the best possible use of each plate when “nesting” the shapes required by our customers. Given the specialised nature of this type of steel it is no great surprise that the majority of our sales are made in cut and processed form.

SUPER DUPLEX STAINLESS STEEL:
Duplex stainless steels are extremely corrosion resistant, work hardenable alloys. Duplex stainless steel plate contains relatively high levels of chromium (between 18% and 28%) and low to moderate amounts of nickel (between 1.5% and 8%). The high corrosion resistance and excellent mechanical properties of duplex stainless steels can be attributed to their chemical composition and balanced (duplex) microstructure of approximately equal volume percentages of ferrite and austenite. Because of this duplex nature, it will display properties characteristic of both austenitic and ferritic stainless steels. Duplex stainless steels are in most cases, tougher than ferritic stainless steels. Strengths of duplex stainless steels can in some cases be double that for austenitic stainless steels.

The high chromium and molybdenum content of Super Duplex makes it extremely resistant to uniform corrosion by organic acids like formic and acetic acid. Super Duplex also provides excellent resistance to inorganic acids, especially those containing chlorides.
The pitting Resistance equivalent of Super Duplex, calculated by PREN = Cr + 3.3Mo + 16N, will exceed 40 in most material forms.
