EN 10025-2 S275J0 High-strength Low-alloy (HSLA) Steel Plate

EN 10025-2 S275J0 is a European standard for hot-rolled structural steel products, commonly used in construction and engineering applications.

EN 10025-2 S275J0 is a reliable, versatile, and economical hot-rolled non-alloy structural steel. It achieves an excellent balance between strength, toughness, weldability, and cost, making it one of the most commonly used and popular steel grades in the fields of construction, engineering machinery, and general structural manufacturing.

Features and Benefits

1. Good balance of strength and toughness: A yield strength of 275 MPa is sufficient for many structural applications, while good toughness at room temperature ensures structural safety.

2. Excellent weldability: Due to its low carbon equivalent, it is well-suited for all conventional welding methods without the need for complex preheating or post-weld heat treatment.

3. Good formability: It can undergo cold working operations such as bending, stamping, and shearing.

4. Cost-effective: As a non-alloy steel, its price is relatively lower than higher-strength alloy steels, offering high cost performance.

* The mechanical properties vary with the thickness of the material—the thicker the plate, the more its yield strength slightly decrease.

1. Building Structures: Such as factory building frames, steel structure residences, support columns, etc.

2. Mechanical Manufacturing: Used for equipment bases, frames, transmission components, etc.

3. Bridges and Municipal Engineering: Small bridge components, guardrails, pipeline supports, etc.

4. Containers and Vehicles: Some freight containers, special vehicle body structures.

Material Characteristics:

Good Mechanical Properties: Moderate yield strength and tensile strength, meeting the general structural load-bearing requirements.

Machinability: Easy to process, including welding, cutting, and bending, making it suitable for fabricating complex structures.

Low-Temperature Toughness: J0 rating ensures impact toughness at 0°C, suitable for outdoor engineering in non-extreme cold regions.
