PROCESSING – HOT FORMING:

The first step in hot forming is to select the appropriate temperature for the plate. Once the plate has been heated to the desired temperature, it is shaped using various tools, such as rollers or presses. This process allows for the creation of complex shapes and designs that would be challenging to achieve using other methods.

One of the significant advantages of hot forming is its ability to produce strong, durable components that can withstand high levels of stress and pressure. This makes it perfect for use in industries such as construction and manufacturing, where toughness and durability are critical.

Another benefit of hot forming is its ability to produce tight tolerances and precise shapes. This is particularly useful in industries where accuracy is essential, such as the aerospace or medical industries

PROCESSING – COLD FORMING:

The cold forming process involves shaping metal at room temperature or slightly above, without the need for excessively high heat. This process is preferred in the processing of the duplex 2205 sheet as it helps to maintain the integrity of the material's properties.

During cold forming, the 2205 duplex plate can be shaped into various forms such as sheet metal, bars, pipes, and fittings. The material can also be subjected to different cold working techniques such as bending, drawing, rolling, and stamping without compromising its unique physical, mechanical, and chemical properties.

Cold forming the 2205 stainless steel sheet offers various benefits, including reduced production costs, flexibility in design, and improved precision in shaping. Additionally, it offers greater strength and durability, excellent resistance to erosion and corrosion, and a long service life.
