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.
