3. Application performance of structural steels
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/mm 2 ;
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 cm 2 ) on a Charpy V specimen at room temperature and, if required, at low temperature.
