Application performance of structural steels
Structural steel

Structural steels are essentially defined by their properties of use.

These properties of use are guaranteed. They are :

• yield strength at 20°C,R_eH expressed in N/mm² ;

• tensile strength at 20 °C,R_m expressed in N/m ;

• elongation at break at 20 °C,A expressed in % ;

• the impact bending fracture energy KV expressed in Joule (also known as resilience, without the value being expressed per cm²) on a Charpy V specimen at room temperature and, if required, at low temperature.

These properties are measured on specimens...
