Properties
These grades comply with the EN 10149-3:2013 standard, which describes normalised or normalised rolled steels.
Normalised or normalised rolled steels are characterised by a guaranteed minimum yield strength, controlled metallurgical purity and a fine grain structure.
Advantages
Like the corresponding grades obtained by thermomechanical rolling, normalised or normalised rolled steels combine excellent mechanical properties, such as high strength, fatigue resistance and toughness, with good formability. Their higher carbon content may affect their weldability. Nevertheless, these grades meet the specifications for normalised steel.
Applications
Normalised or normalised rolled steels are mainly used for the construction of bridges, containers, pylons and other architectural structures.
Available options
Options available (after prior agreement):
- Reduced carbon equivalent value
- Reduced sulphur content
- Vacuum degassing
- Other options specified in the standard
