Apr 3, 2025 · S355 Steel, as per the EN 10025-2 standard, offers a yield strength of around 355 MPa and tensile strength between 470-630 MPa, varying slightly depending on the specific sub-grades (JR, J0, J2, K2). It is known for its good weldability and toughness.

S355J2 steel (1.0577) is a quality grade of S355 steel, which is one of the non-alloy structural steels commonly used in Europe. According to EN 10025-2: Hot rolled products of structural steels, S355 steel is divided into 4 quality grades, namely: S355K2 (1.0596), previous names: S355K2G3 and S355K2G4 in EN 10025:1990.

Aug 23, 2015 · S355 is a non-alloy European standard (EN 10025-2) structural steel, most commonly used after S235 where more strength is needed. It got great weldability and machinability, let us see more mechanical details of this steel.

S355 features high strength, good weldability, and moderate toughness, making it ideal for construction, bridges, wind turbines, and heavy machinery. It has several subgrades based on impact energy: S355JR (27J at +20°C), S355J0 (27J at 0°C), S355J2 (27J at …

Apr 3, 2025 · S355: This grade has a higher yield strength of 355 MPa, making it ideal for high-stress applications such as high-rise buildings and offshore structures. Its increased strength and durability are critical in these demanding environments.

Apr 4, 2025 · S355 steel is a high-strength, low-alloy structural steel with a minimum yield strength of 355 MPa. It has a tensile strength of about 450 – 680 MPa, good impact resistance with a minimum energy of 27 J at specified temperatures, and a density of approximately 7850 kg/m³.
