Possible applications of special material 1.4462 Duplex

Material 1.4462 – just one step below the “king”
of special materials in stainless steel

If material 1.4529 is our “king” among the special materials, then material 1.4462 is hardly inferior and just one step below it. To stay with the visual language of chess, 1.4462 stainless steel could be considered the “queen” of our special materials due to its versatility. Another name for it is duplex steel or just 1.4462 Duplex. This special material is a stainless, austenitic-ferritic stainless steel. Ferritic stainless steels have a chromium content between 12% and 18% with a very low carbon content of less than 0.2%. The special material demonstrates high strength and good corrosion resistance due to this combination. It is classified in Corrosion Resistance Class (CRC) IV as a result and demonstrates good resistance to intergranular corrosion or pitting.
The combination of the properties of austenite and ferrites in a single material opens up a wide variety of applications. Our customers particularly like to take advantage of our large stock of 1.4462 threaded rods. We can also offer our customers a cutting service for 1.4462 threaded rods on request.

The key properties of material 1.4662 Duplex

This special material combines high strength and very good corrosion properties in a single material. It is also resistant to surface corrosion and pitting. The stability of this duplex steel does not even suffer at higher temperatures or in environments containing sulphur and chloride. The material demonstrates good wear properties in terms of fatigue or erosion. Further beneficial properties of this stainless steel include its good weldability and low thermal expansion coefficient.

The applications for 1.4462 Duplex
stainless steel in connection technology

This two-phase, rust-resistant duplex stainless steel with beneficial mechanical properties offers a wide range of applications in connection technology. It is frequently favoured for use in the immediate splash water area up to 250 meters from the sea.

It is also used, for example, in offshore installations or building facades built directly next to the sea. Connecting elements made of
this stainless steel are also used on oil platforms railings, load-bearing components, stairs and ladders or substructures for helidecks.

In short, this duplex steel is the ideal solution for connecting anything seaside that is attacked by chlorides or salt water.
