What are the typical sizes available for duplex stainless steel products?

Duplex stainless steel is a remarkable material that combines the best of both austenitic and ferritic stainless steels. It offers high strength, excellent corrosion resistance, and good weldability, making it a popular choice in various industries such as chemical processing, oil and gas, and marine applications. As a leading supplier of duplex stainless steel products, I often receive inquiries about the typical sizes available. In this blog post, I'll delve into the common sizes for different types of duplex stainless steel products.

Duplex Stainless Steel Plates

Duplex stainless steel plates are widely used in construction, pressure vessels, and structural applications. The thickness of these plates can vary significantly depending on the specific requirements of the project. Generally, the thickness of duplex stainless steel plates ranges from 3mm to 100mm. Thinner plates, around 3 - 6mm, are often used in applications where weight is a concern, such as in some marine structures or lightweight equipment. Medium - thickness plates, from 6mm to 25mm, are commonly employed in pressure vessels and general construction. For heavy - duty applications like large - scale industrial structures or high - pressure equipment, thicker plates of 25mm to 100mm are used.

In terms of width and length, standard widths of duplex stainless steel plates usually range from 1000mm to 2500mm. The length can be up to 12000mm, although custom lengths can also be provided according to customer needs. These standard sizes are designed to balance the requirements of transportation, handling, and fabrication. For example, a width of 1500mm and a length of 6000mm is a very common size that is easy to cut and assemble in most fabrication shops.

Duplex Stainless Steel Pipes

Duplex stainless steel pipes are essential in fluid transportation systems, especially in corrosive environments. The outer diameter (OD) of duplex stainless steel pipes can vary from as small as 6mm to as large as 1200mm. Small - diameter pipes, with an OD of 6 - 50mm, are often used in instrumentation, small - scale chemical processing, or in some precision engineering applications. Medium - diameter pipes, ranging from 50mm to 300mm, are commonly found in general industrial piping systems, such as water supply and drainage in chemical plants. Large - diameter pipes, with an OD of 300mm to 1200mm, are used in major infrastructure projects like oil and gas pipelines or large - scale water treatment plants.

The wall thickness of duplex stainless steel pipes also varies according to the application and the pressure requirements. It can range from 1mm to 50mm. Thin - walled pipes, with a wall thickness of 1 - 3mm, are suitable for low - pressure applications or where flexibility is needed. Medium - walled pipes, with a thickness of 3 - 10mm, are used in most standard industrial piping systems. Thick - walled pipes, with a wall thickness of 10 - 50mm, are required for high - pressure applications, such as in deep - sea oil and gas extraction.

Duplex Stainless Steel Bars

Duplex stainless steel bars are used in a variety of applications, including fasteners, shafts, and structural components. The diameter of round bars typically ranges from 6mm to 300mm. Small - diameter bars, around 6 - 20mm, are often used for making small fasteners like screws and bolts. Medium - diameter bars, from 20mm to 100mm, are used in general mechanical engineering applications, such as shafts and connecting rods. Large - diameter bars, with a diameter of 100mm to 300mm, are used in heavy - duty structural applications or for manufacturing large - scale machine parts.

Square and rectangular bars are also available in various sizes. The side length of square bars can range from 10mm to 200mm, while the dimensions of rectangular bars can vary widely depending on the application. For example, a common size for rectangular bars might be 20mm x 50mm, which can be used in the construction of frames or in some custom - made mechanical components.

Specialized Duplex Stainless Steel Products

In addition to the common plates, pipes, and bars, we also offer specialized duplex stainless steel products. For example, Heat Resistant Steel Hood is a product designed to withstand high temperatures and corrosive environments. The size of heat - resistant steel hoods can be customized according to the specific requirements of the industrial furnace or equipment they are intended for.

Another specialized product is the Heat Resistant Steel Tray. These trays are used in heat - treating processes and other high - temperature applications. The size of the trays can vary from small laboratory - scale trays to large industrial - scale ones, with lengths ranging from 200mm to 2000mm, widths from 100mm to 1500mm, and depths from 20mm to 200mm.

We also provide The Coated Sand Casting Casting products made from duplex stainless steel. The size of these castings depends on the complexity and the end - use of the part. They can range from small, intricate components with dimensions in the millimeter range to large, heavy - duty parts with dimensions in the meter range.

Custom Sizes and Applications

While the above are the typical sizes available, we understand that many projects have unique requirements. That's why we offer custom - sizing services for all our duplex stainless steel products. Whether you need a plate with a non - standard thickness, a pipe with an unusual diameter, or a specialized component with a custom shape, our experienced team can work with you to meet your exact specifications.

Our duplex stainless steel products have been used in a wide range of industries. In the oil and gas industry, they are used in offshore platforms, pipelines, and refineries to withstand the harsh corrosive environment of saltwater and chemicals. In the chemical processing industry, our products are used in reactors, storage tanks, and piping systems to handle various corrosive chemicals. In the marine industry, duplex stainless steel is used in shipbuilding, marine structures, and desalination plants due to its excellent corrosion resistance in seawater.
