EN10025-3 S275N is a normalized rolled structural steel plate grade that is widely used in the construction industry due to its excellent mechanical properties and versatility. This grade is part of the European standard for hot-rolled structural steel products and is particularly suited for applications that require high strength and good toughness at low temperatures.

Chemical Composition:

The chemical composition of S275N is strictly controlled to ensure the material's mechanical properties and weldability. The typical chemical composition includes the following elements (in weight percentage):

· Carbon (C): ≤ 0.20%

· Silicon (Si): ≤ 0.55%

· Manganese (Mn): ≤ 1.60%

· Phosphorus (P): ≤ 0.035%

· Sulfur (S): ≤ 0.035%

· Aluminum (Al): ≥ 0.020%

· Niobium (Nb): ≤ 0.05%

· Titanium (Ti): ≤ 0.04%

· Vanadium (V): ≤ 0.12%

Mechanical Properties:

The mechanical properties of S275N are characterized by its high strength and good ductility. The minimum values for these properties are as follows:

· Yield Strength: ≥ 275 MPa

· Tensile Strength: 430 - 570 MPa

· Elongation: ≥ 22%

· Impact Energy : ≥ 27 Joules

Heat Treatment State:

S275N steel plates are supplied in the normalized state, which involves heating the steel to a specific temperature and then cooling it in air to improve its mechanical properties. This process ensures that the material has a uniform microstructure and good toughness.

Low-Temperature Impact Test:

The material is subjected to a low-temperature impact test at -20°C to ensure that it maintains its toughness and impact resistance in cold environments. This is particularly important for structures that will be exposed to low temperatures.

Available Dimensions:

TJC Steel Group offers S275N structural steel plates in a wide range of sizes to meet the requirements of various applications. The typical thickness range is from 6mm to 200mm, with widths up to 3900mm and lengths up to 12000mm. Custom sizes are also available upon request.

Main Applications:

S275N steel plates are commonly used in the construction of bridges, offshore structures, power plants, and other engineering and construction projects that require high strength and good toughness. The material's ability to withstand low temperatures makes it suitable for use in cold climates and offshore environments.
