S275JR (General Structural Steel – EN 10025-2) S275JR is a popular non-alloy structural steel grade covered under the EN 10025-2 standard, known for its dependable mechanical strength and excellent processing characteristics. With a minimum yield strength of 275 MPa, this steel is well-suited for structural elements in construction and general engineering. The “JR” designation signifies that the material has been Charpy impact tested at 27 Joules at room temperature (+20°C), confirming its basic toughness and suitability for structural applications. Key Features: Minimum yield strength of 275 MPa, ideal for moderate-load structures Excellent weldability and workability, allowing ease of fabrication Room-temperature impact tested (27J @ 20°C) for standard safety requirements Widely available in hot-rolled sections, sheets, and structural components Typical Mechanical Properties: Property S275JR Yield Strength ≥ 275 MPa Tensile Strength 410–560 MPa Elongation ≥ 20% Impact Resistance ≥ 27 J at +20°C Weldability Very good Common Applications: Structural frameworks in civil and industrial buildings I-beams, U-channels, angles, and steel plates Base structures and fabrication in machinery and equipment Platforms, support systems, and mild load-bearing parts Infrastructure and agricultural equipment frames Summary: S275JR is a reliable and cost-efficient structural steel option used extensively across construction and fabrication sectors. With its balanced mechanical properties and ease of processing, it provides a practical choice for a wide range of general structural applications.
