Types of Duplex Stainless Steel Plates
Lean Duplex Stainless Steel Plates
Lean duplex stainless steel plates have a low nickel content, which makes them more affordable than other types of duplex stainless steel plates. They contain around 17-18% chromium and 4-6% nickel, making them ideal for use in applications where corrosion resistance is required but not at high levels.

FAQ
Duplex stainless steel is a type of stainless steel that contains both austenitic and ferritic microstructures.both stainless steel and duplex stainless steel offer corrosion resistance, duplex stainless steel stands out for its enhanced corrosion resistance, strength, and toughness, making it suitable for demanding applications in aggressive environments.
The most commonly used duplex stainless steel in Maharashtra,like in many other parts of the world, is UNS S31803, also known as 2205 duplex stainless steel. This alloy is widely utilized in various industries due to its excellent combination of corrosion resistance, high strength, and good weldability.
A material referred to as “22Cr duplex” typically indicates a type of duplex stainless steel with a chromium (Cr) content of approximately 22%. Duplex stainless steels are characterized by their two-phase microstructure, consisting of both austenite and ferrite phases. The balanced combination of these phases gives duplex stainless steels their desirable properties, including high corrosion resistance and good mechanical strength.
Duplex stainless steel, such as Duplex 2205, is available in a wide range of standard sizes for various products like pipes, tubes, sheets, and bars.
Duplex Pipe and Tubing- common sizes like 1/2″, 3/4″, 1″, 2″, 3″, 4″, 6″, 8″, 10″, and 12″ and sometimes larger.
Duplex Sheet and Plate-Standard sheet sizes may include 1000mm x 2000mm, 1219mm x 2438mm (4ft x 8ft), and larger.
Duplex Round Bars and Rods-Standard lengths for round bars are typically 12 feet (3.66 meters) or 20 feet (6.1 meters), but custom lengths can be ordered.
Duplex Fittings -Duplex fittings, such as elbows, tees, reducers, and flanges, come in various sizes, usually ranging from 1/2″ to 12″ or larger.
