Mechanical properties of S275J2G3 steel plate

S275J2G3 steel plate is a European standard non-alloy structural steel, corresponding to the European standard steel number 1.0144, according to EN 10025 standard. The "G3" suffix usually indicates normalizing rolling.

S275J2G3 steel plate features:

 

Excellent mechanical properties: S275J2G3 steel plate has good yield strength, tensile strength, toughness, fatigue resistance and impact resistance, and can adapt to a variety of complex working environments.

 

Wide range of applications: Because of its excellent performance, S275J2G3 steel plate has a wide range of applications in construction, bridge, vehicle manufacturing, machinery manufacturing, ship construction and other fields.

 

Good workability: The steel plate not only has good plasticity and weldability, but also has high cutting accuracy, making it the material of choice for architects and structural engineers.

 

Chemical composition of S275J2G3 steel plate:

 

Carbon (C) : ≤0.18% (thickness t≤150mm) or ≤0.2% (thickness t>150mm)

 

Manganese (Mn) : ≤1.5%

 

Phosphorus (P) : ≤0.035%

 

Sulfur (S) : ≤0.035%

 

Nitrogen (N) : ≤0.12%

 

Mechanical properties of S275J2G3 steel plate:

 

Yield strength: Depending on the thickness of the steel plate, the yield strength varies between 215MPa and 275MPa. For example, when the thickness of the steel plate is between 1.5mm and 2mm, the yield strength is ≥275MPa; When the thickness of the steel plate is between 150mm and 200mm, the yield strength is reduced to ≥215MPa.

 

Tensile strength: between 400MPa and 580MPa, depending on the thickness of the steel plate.

 

Elongation: As the thickness of the steel plate increases, the elongation gradually decreases, from ≥23% to ≥17%.

 

Impact work: At different temperatures, steel plates need to meet specific impact work requirements to ensure their toughness in low temperature environments.
