The “+N” signifies a normalized delivery condition that enhances toughness. Mechanically, these steels boast a minimum yield strength of 355 MPa and a tensile strength ranging from 470 to 630 MPa. They also offer good impact resistance at 0°C, adhering to EN 10025-2 standards. These characteristics make S355JO+N an excellent choice for high-stress structural applications.
