S275J2 H-beam
Within the first 100 words, it is essential to clarify that we are the manufacturer, not a distributor. GNEE controls steelmaking, rolling, heat treatment, and inspection processes. By managing the entire production chain, we ensure that S275J2 H-beam structural steel meets strict European standards and project-specific requirements.
S275J2 H-beams are widely used where moderate strength, good toughness, and cost efficiency are required, especially in building structures, industrial frameworks, and energy-related projects.
Chemical Composition of S275J2 H-Beam Steel
The chemical composition of S275J2 H-beam steel is strictly controlled to guarantee strength stability, weldability, and long-term structural safety.
| Element | Maximum Content (%) |
|---|---|
| Carbon (C) | ≤ 0.21 |
| Manganese (Mn) | ≤ 1.50 |
| Phosphorus (P) | ≤ 0.035 |
| Sulfur (S) | ≤ 0.035 |
| Copper (Cu) | ≤ 0.55 |
Low carbon content improves welding performance, while controlled manganese content enhances strength and toughness. This balanced composition makes S275J2 suitable for welded H-beam structures used in large-scale construction.
Mechanical Properties of S275J2 H-Beam
The mechanical performance of S275J2 H-beams ensures safe load-bearing capacity under static and dynamic conditions.
| Property | Value |
|---|---|
| Yield Strength | ≥ 275 MPa |
| Tensile Strength | 430–580 MPa |
| Elongation | ≥ 23% |
| Impact Test | 27 J at –20°C (J2) |
The J2 impact requirement guarantees reliable toughness at low temperatures, reducing the risk of brittle fracture in cold climates or outdoor structural applications.

What is the difference between S275JR and S275J2?
The main difference among the three S275 steel lies in their impact temperature: 20℃ of S275JR steel, -20℃ of S275J2 steel and 0℃ of S275J0 steel. What material is S275J2? S275J2 is a low carbon, high tensile strength structural steel which can be readily welded to other weldable steel
What is S235J2 material equivalent to?
EN10025 S235J2 is a carbon steel grade with good structural properties. Some common equivalent materials for EN10025 S235J2 carbon steel plate include: ASTM A36: A widely used structural steel in the U.S. that has similar properties in terms of tensile strength and yield strength.
What is the meaning of s275j2?
"S" denotes that it's a structural steel, while "275" indicates a minimum yield strength of 275 megapascals. The "J2" implies that the steel provides a specified minimum impact energy of 27 joules at -20°C, making it suitable for colder climates.
What does the JR stand for in S235JR?
The alphabet S means that the steel plates are structural. The number 235 means, steel's yield strength. The word JR stands for that the steel grade has undergone a Charpy impact test and is of high quality. The S235JR is a specification given to it, with each symbol indicating something different.
What is equivalent to s235jr2?
EN 10025-2 S235JR is equivalent to ASTM A283 Gr C, DIN ST37-2, JIS SS330, and GB Q235B, with similar moderate strength and weldability for general construction.
