S275JR (Non-Alloy Structural Steel – EN 10025-2) S275JR is a widely used non-alloy structural steel grade specified under EN 10025-2, offering reliable strength, excellent weldability, and consistent performance in general construction and engineering applications. With a minimum yield strength of 275 MPa, it is suitable for moderately stressed structural components across a wide range of industries. The “JR” designation indicates that the material has undergone Charpy V-notch impact testing at 27 Joules at room temperature (≈20°C), ensuring basic toughness for standard structural uses. Key Features: 275 MPa minimum yield strength, ideal for general-purpose structural fabrication Good weldability and machinability with standard fabrication processes Impact-tested at room temperature (27J @ +20°C) for improved safety assurance Suitable for hot-rolled structural profiles, plates, and bars Typical Mechanical Properties: Property S275JR Yield Strength ≥ 275 MPa Tensile Strength 410–560 MPa Elongation ≥ 20% Impact Resistance ≥ 27 J at +20°C Weldability Excellent Common Applications: Structural frames and supports in buildings and bridges Beams, angles, channels, and steel profiles General engineering and fabrication works Base plates, frames, and platforms Agricultural and construction machinery components Summary: S275JR provides a cost-effective and versatile structural steel solution for civil construction, mechanical fabrication, and industrial frameworks. Its consistent mechanical properties and ease of processing make it one of the most trusted grades in the steel industry.
