Uranus® 2304 - Industeel Stainless heavy plates

DESCRIPTION

URANUS® 2304 (UNS S32304 – 1.4362) is a 23% Cr, 4% Nickel, Mo free duplex stainless steel (23.04).

The alloy UR 2304 has similar corrosion resistance properties similar to 316L. Furthermore, its mechanical properties i.e. yield strength, are twice those of 304/316 austenitic grades.

This allows the designer to save weight, particularly for properly designed pressure vessel applications. The alloy is particularly suitable for applications covering the -50°C/+300°C (-58°F/572°F) temperature range. Lower temperatures may also be considered, but need some restrictions, particularly for welded structures.

With its duplex microstructure, low nickel and high chromium contents, the alloy has improved stress corrosion resistance properties compared to 304 and 316 austenitic grades.
 


Uranus® 35N was used in the façade of the French Ministry for
Culture and Communications, in Paris. Architect Francis Soler.

APPLICATIONS


The main supporting arch structure of Arco Malizia in Siena,
Italy, is entirely made of UR® 35N lean duplex stainless steel.

- Generally where 304 and 316L are used
- Pulp and paper industry (chip storage tank, white and black liquor tanks...)
- Caustic solutions, organic acids (SCC resistance)
- Food industry
- Safety panels (high mechanical properties)
- Pressure vessels (weight savings...)
- Mining (abrasion/corrosion)
