Duplex Plate

Duplex plate

What is a Duplex Plate?

These plates get manufactured from a unique iron alloy comprising chromium and nickel. A DSS plate has ferritic and austenitic phases – a microstructure that lends excellent strength and corrosion resistance. A DSS sheet is available in different grades and compositions for heavy industries like oil and gas, petrochemicals, construction, and chemical processing.

Does a duplex steel plate rust?

Dependable rust resistance is a coveted property of a DSS plate. It benefits from the 50-50% combination of austenitic and ferrite grades. The additions of chromium, molybdenum, and nitrogen make it corrosion-resistant. A DSS perforated sheet resists rust for a long service duration. Moreover, it is fairly easy to clean and maintain.

Which industries commonly use DSS plates and for what applications?

These products bundle exciting properties like heat conductivity, good strength, and tolerance to corrosion in different forms like cracking and pitting. It can operate in temperatures from -50°C to 316°C. These properties let a DSS plate work effectively in wastewater treatment, paper processing, and marine industries. A DSS foil also works in heat exchangers and superheater tubes because of its thermally stable nature.

What are the standard quality testing protocols for DSS plates?

Non-destructive testing (NDT) of a DSS plate helps ensure adherence to international specifications. The typical methods are radiography, ultrasonic testing, and Eddy Current. Manufacturers also perform magnetic particle inspection, dye penetrant testing, or a third-party check for a DSS checker plate.

How does the corrosion resistance of DSS plates compare to other materials?

The most attractive trait of these plates is their strength and corrosion resistance. A DSS plate is not damaged even when exposed to chlorides and sulphides. Compared to stainless steel, it has a much superior PREN of 33 compared to a corresponding value of 22-27 for Grade 316. However, a DSS sheet has lower tolerance against erosion than super duplex material or more expensive metals like titanium.

What is the typical price range for DSS plates of different sizes and grades?

Prices vary by the grades and dimensions of DSS strips. So, for example, 2205 grade costs around Rs 300 to 450 per kilogram. But Grade 2304 is cheaper because of its lower nickel content. The standard thicknesses of a duplex sheet are 4 to 5mm and above 5mm.
