Duplex

Duplex steel is a group of corrosion resistant alloys that contain two main crystal structures: austenitic (similar to stainless steel) and ferritic (similar to corrosion resistant stainless steel). This combination of structures makes Duplex steel a unique material with an  excellent combination of mechanical strength and corrosion resistance.

What are the characteristics of Duplex steel?

Duplex steel is highly resistant to corrosion in aggressive environments such as sea salt, sulfuric acid, organic acids, chlorine and chloride. It is therefore an ideal choice for applications in chemical processing, marine and oil industries.

This material has significantly greater mechanical strength compared to conventional stainless steels. Its tensile strength is significantly higher, making it an ideal material for heavy-duty applications. Duplex steel is relatively easy to machine and form, allowing for the production of a variety of shapes and products. It can be forged, rolled, or cold-worked, which increases its versatility in the industry.

This metal retains its properties even at relatively high temperatures, making it suitable for applications where the operating temperature is relatively high, such as in industrial equipment or heat exchangers. This type of steel has good impact and shock resistance, making it useful in applications where resistance to mechanical damage is important, such as in machine structures or industrial equipment.
