Duplex Stainless Steels

Duplex stainless steels have a ferritic-austenitic microstructure, in roughly equal proportions 50% ferrite and 50% austenite. Duplex combines many of the attractive properties of ferritic and austenitic stainless steels into one.

Different variants for Duplex

Duplex stainless steels are designed to provide better corrosion resistance, in particular to stress corrosion and pitting corrosion. The microstructure leads to higher strength than standard austenitic stainless steels such as Type 304 or 316. Duplex stainless steels have become more and more popular in recent years. There are several variants available, such as Duplex 2205, Superduplex 2507 or lean duplex with lower nickel content.

The advantages of Duplex Stainless Steels

Corrosion Resistance: Duplex stainless steel has excellent corrosion resistance due to its high chromium and molybdenum content. It is particularly resistant to stress corrosion cracking and pitting, which makes it suitable for use in harsh environments. There are several variants available, such as Duplex 2205, Superduplex 2507 or lean duplex with lower nickel content.

Strength: Duplex stainless steel is much stronger than conventional austenitic stainless steels, which allows for thinner and lighter constructions without sacrificing durability.

Toughness: Duplex stainless steel has a high toughness, which means it is resistant to brittle fracture and impact. This property makes it suitable for use in cryogenic applications.

Cost-effectiveness: Although duplex stainless steel is more expensive than conventional austenitic stainless steels, its superior properties can lead to cost savings in the long run by reducing maintenance and downtime.

Versatility: Duplex stainless steel can be used in a wide range of applications, including chemical processing, oil and gas, marine, and pulp and paper industries. It is also used in construction and architecture due to its aesthetic appeal.
