EN S235JR High Manganese, Structural, Hot Rolled, Base Steel, t < 16 mm Product Information -:- For detailed product information, please contact sales. -: **Product Name:** EN S235JR Structural Steel, Hot Rolled, Base Material, Thickness t ≤ 16 mm **Overview:** EN S235JR is the **most fundamental and widely used non-alloy structural steel** in Europe, defined as a **base material** under the EN 10025-2 standard. The "JR" designation indicates the baseline quality level, with impact properties verified at room temperature (+20°C). It is supplied in the hot-rolled condition and is characterized by excellent weldability, good formability, and high cost-effectiveness. For thicknesses **≤ 16 mm**, it achieves its highest guaranteed yield strength. It is critical to note that **S235JR is NOT a "High Manganese" steel**; it is a standard carbon-manganese steel with typical manganese levels. **Key International Standards:** * **Primary Standard:** **EN 10025-2:2019** - Hot rolled products of structural steels - Part 2: Technical delivery conditions for non-alloy structural steels. * **Grade & Quality Designation:** **S235JR** * **S:** Structural Steel * **235:** Minimum yield strength (ReH) in MPa for thicknesses **≤ 16 mm**. * **JR:** Basic quality. **'J'** = Impact tested; **'R'** = Test temperature is **Room Temperature (+20°C)**. * **Clarification on "High Manganese":** This is a **misleading and incorrect classification**. S235JR has a standard manganese content for its class and is not chemically distinguished by high manganese. Its key attribute is its status as the **economical base grade**. * **Common International Equivalents:** * **ASTM:** **A36** (closest general-purpose equivalent). * **JIS:** **SS400**. * **GB/T:** **Q235B**. * **ISO:** **Fe360B** as per ISO 630-2. **Chemical Composition (Ladle Analysis, % by weight, maximum values per EN 10025-2 for t ≤ 16 mm):** Standard composition for maximum manufacturability. * **Carbon (C):** ≤ **0.17%** * **Manganese (Mn):** ≤ **1.40%** (This is a standard upper limit, not a high level. Content is typically lower for thin sheets to aid formability). * **Phosphorus (P):** ≤ **0.045%** * **Sulphur (S):** ≤ **0.045%** * **Nitrogen (N):** ≤ **0.014%** (for killed steel, may be higher for rimming steel in thin sheets). * **Note:** For thin hot-rolled sheet (t < 3mm), it may be supplied as "rimming steel," which has lower silicon content and different solidification characteristics. **Physical & Mechanical Properties (for hot-rolled condition, thickness t ≤ 16 mm):** This is the optimal thickness range for achieving the full nominal strength. * **Yield Strength (ReH):** ≥ **235 MPa** (This is the **highest guaranteed minimum** for this grade, applicable only to t ≤ 16mm). * **Tensile Strength (Rm):** **360 - 510 MPa**. * **Elongation at Break (A5):** ≥ **26%** (Minimum, longitudinal test piece. Demonstrates excellent ductility). * **Impact Energy (KV):** ≥ **27 J at +20°C** (Longitudinal, Charpy V-notch). **CRITICAL LIMITATION:** No guaranteed toughness below +20°C. * **Density:** **7.85 g/cm³**. * **Modulus of Elasticity:** **210 GPa**. * **Poisson's Ratio:** **0.3**. **Product Features:** 1. **Optimal Strength in Thin Sections:** Delivers its full nominal yield strength (235 MPa) in this thickness range, offering the best weight-to-strength ratio for this grade. 2. **Exceptional Weldability and Formability:** The low carbon content and thin gauge make it extremely easy to weld (no pre-heat typically required) and cold form (bend, roll, stamp). 3. **Maximum Cost Efficiency:** The most economical entry point for structural steel components, offering proven performance for a vast array of non-critical applications. 4. **Availability:** The most readily available steel grade in a wide variety of forms (sheet, strip, sections). **Typical Applications (for t ≤ 16 mm):** S235JR in thin sections is ubiquitous in light construction and general manufacturing. * **Light Construction:** **Purlins, girts, cladding rails, and light framing sections** (often cold-formed from hot-rolled coil). * **General Fabrication:** **Machine guards, cabinets, covers, brackets, and platforms**. * **Automotive & Transport:** **Non-critical trailer body panels, internal reinforcements, and container sheathing**. * **Storage & Furniture:** **Shelving units, racking components, and industrial furniture**. * **Ductwork & Enclosures:** **Ventilation ducts, cable trays, and electrical enclosures**. **Available Forms & Processing (for t ≤ 16 mm):** * **Forms:** **Hot-rolled sheet and strip** (in coils or cut lengths), **flat bars**, and **light structural sections** (angles, channels). * **Surface:** Typically with mill scale. Commonly available as **pickled and oiled (PO)** for painting or further processing. * **Processing:** Ideal for **shearing, punching, laser/plasma cutting, roll-forming, and all types of welding**. --- **Critical Selection & Procurement Note:** * **Temperature Warning:** The **JR quality is unsuitable for any application where the service temperature can fall below 0°C**, especially if dynamic loads or impact are involved. For such uses, **S235J0 (0°C) or S235J2 (-20°C)** must be specified. * **Thickness-Strength Relationship:** This is the reference thickness for the 235 MPa yield strength. For thicker material, the guaranteed yield strength decreases (e.g., ≥225 MPa for t > 40mm). * **Correct Terminology:** Avoid using the term "High Manganese." The correct description is **"Non-Alloy Base Structural Steel."** * **Specification:** For thin sheet, it is advisable to specify if **killed or rimming steel** is required based on the forming and welding process. For most fabrication, killed steel is preferred. -:- For detailed product information, please contact sales. -: EN S235JR High Manganese, Structural, Hot Rolled, Base Steel, t < 16 mm Specification Dimensions Size： Diameter 20-1000 mm Length <5812 mm Size:We can customized as required Standard： Per your request or drawing We can customized as required Properties（Theoretical） Chemical Composition -:- For detailed product information, please contact sales. -: EN S235JR High Manganese, Structural, Hot Rolled, Base Steel, t < 16 mm Properties -:- For detailed product information, please contact sales. -:
