S235JR – General Structural Steel for Everyday Engineering S235JR is a widely used non-alloy structural steel grade under the EN 10025-2 standard. With a minimum yield strength of 235 MPa and reliable toughness at room temperature (as indicated by the 'JR' designation), this material is ideal for structural and fabrication work in a variety of industries. Thanks to its low carbon content, S235JR offers excellent weldability, machinability, and formability, making it well-suited for mild to moderately loaded structural applications where cost-effective and consistent material performance is important. Main Characteristics: Complies with European standard EN 10025-2 Reliable for structural frames and supports Good surface quality and formability Can be welded without preheating Suitable for galvanizing and surface coatings Chemical Composition (% Typical): Element Content Carbon (C) ≤ 0.17% Manganese ≤ 1.40% Phosphorus ≤ 0.035% Sulfur ≤ 0.035% Nitrogen ≤ 0.012% Mechanical Properties: Property Value (Approx.) Yield Strength ≥ 235 MPa Tensile Strength 360 – 510 MPa Elongation ≥ 25% Impact Resistance ≥ 27 J @ 20°C Typical Uses: Structural beams, columns, and frames General fabrication and steel structures Platforms, walkways, and base plates Equipment supports and light engineering Parts requiring forming, welding, or cutting Conclusion: S235JR provides a dependable and economical solution for a wide range of structural and engineering needs. Its combination of strength, versatility, and ease of processing makes it a popular choice for manufacturers, builders, and fabricators looking for consistent performance in non-extreme conditions.
