S275JR steel plates are widely used structural steel materials designed for engineering and construction applications that require higher strength than standard structural steels. Produced according to the EN 10025-2 standard, S275JR plates provide reliable mechanical strength, good weldability, and excellent structural performance.
Because of their balanced mechanical properties and durability, S275JR steel plates are commonly used in infrastructure projects, steel structures, bridges, industrial fabrication, and heavy engineering components. With a minimum yield strength of 275 MPa, S275JR provides stronger load-bearing capability compared to lower-grade structural steels such as S235JR.
Hindustan Steel Corporation supplies S275JR steel plates to engineering companies, construction contractors, and industrial manufacturers worldwide. Our plates are sourced from internationally approved mills and comply with global quality standards.
S275JR is a non-alloy structural steel grade defined under the European standard EN 10025-2. It is designed for structural applications where moderate to high strength and good weldability are required.
The designation S275JR represents the following:
| Symbol | Meaning |
|---|---|
| S | Structural Steel |
| 275 | Minimum Yield Strength (MPa) |
| JR | Impact Tested at +20°C |
Because of its strength and structural reliability, S275JR plates are widely used for structural engineering, construction frameworks, bridges, and machinery fabrication.
The manufacturing process of S275JR steel plates involves controlled steelmaking and rolling procedures to achieve consistent mechanical properties.
Steel production begins with melting raw materials using electric arc furnace or basic oxygen furnace technology. The molten steel is then cast into slabs.
These slabs undergo hot rolling to achieve the desired thickness and plate dimensions. The rolling process refines the grain structure of the steel and improves its mechanical properties.
After rolling, the plates are inspected and tested to ensure they meet the chemical composition and mechanical property requirements defined by EN 10025 standards.
| Property | Specification |
|---|---|
| Standard | EN 10025-2 |
| Grade | S275JR |
| Yield Strength | Minimum 275 MPa |
| Tensile Strength | 410 – 560 MPa |
| Thickness Range | 5 mm – 200 mm |
| Width | Up to 3000 mm |
| Length | Up to 12000 mm |
These specifications allow S275JR plates to perform effectively in structural applications requiring reliable strength.
| Element | Maximum (%) |
|---|---|
| Carbon | 0.21 |
| Manganese | 1.50 |
| Phosphorus | 0.035 |
| Sulfur | 0.035 |
| Nitrogen | 0.012 |
The controlled chemical composition improves weldability, machinability, and structural durability.
| Property | Value |
|---|---|
| Yield Strength | ≥ 275 MPa |
| Tensile Strength | 410 – 560 MPa |
| Elongation | ≥ 23% |
| Impact Energy | 27J at +20°C |
These properties ensure structural reliability and load-bearing capability for engineering applications.
