EN 10025-2 S235JR S235J0 S235J2 S275JR S275J0 Structural Steel Pipe
Introduction
EN 10025-2 is a European standard that specifies the technical delivery conditions for hot-rolled non-alloy structural steel products. This standard covers various grades of structural steel, including S235JR, S235J0, S235J2, S275JR, and S275J0, which are widely used in construction and engineering applications.
Material Specification
The structural steel grades specified in EN 10025-2 are characterized by their yield strength, tensile strength, and impact toughness. These properties make them suitable for various structural applications, including buildings, bridges, and other infrastructure projects.
Key Features
- Hot Rolled: The steel is processed at high temperatures, which enhances its ductility and workability.
- Non-Alloy: These grades do not contain significant amounts of alloying elements, making them cost-effective.
- Good Weldability: The low carbon content allows for easy welding and fabrication.
- Versatile Applications: Suitable for a wide range of structural applications.

Mechanical Properties
| Grade | Yield Strength (MPa) | Tensile Strength (MPa) | Elongation (%) | Impact Energy (J) at -20°C |
| S235JR | 235 | 360-510 | ≥ 26 | 27 |
| S235J0 | 235 | 360-510 | ≥ 26 | 27 |
| S235J2 | 235 | 360-510 | ≥ 26 | 40 |
| S275JR | 275 | 430-580 | ≥ 22 | 27 |
| S275J0 | 275 | 430-580 | ≥ 22 | 27 |
Steel Grade
- S235JR: General structural steel with a minimum yield strength of 235 MPa.
- S235J0: Similar to S235JR but with improved impact properties at lower temperatures.
- S235J2: Offers higher impact resistance at even lower temperatures.
- S275JR: Higher yield strength of 275 MPa, suitable for more demanding applications.
- S275J0: Enhanced impact properties compared to S275JR.
Application
These structural steel grades are commonly used in:
- Construction of buildings and bridges
- Manufacturing of structural components
- Heavy machinery and equipment
- General engineering applications
Possible Alternative Grades
- S355: A higher strength grade that can be used in applications requiring greater load-bearing capacity.
- S420: Suitable for high-strength applications, offering improved mechanical properties.
