EN S235JRG1 High Manganese, Structural, Hot Rolled, Base Steel Product Information -:- For detailed product information, please contact sales. -: **Product Name:** EN S235JRG1 Structural Steel, Hot Rolled, Base Material **Overview:** EN S235JRG1 is a **non-alloy base structural steel** specified under the EN 10025-2 standard, belonging to the S235 strength category. The designation **"G1"** signifies the steel is supplied in a specific condition: **hot-rolled, without a defined requirement for normalizing or thermomechanical rolling, but typically implying as-rolled with guaranteed mechanical properties.** This grade provides the fundamental combination of yield strength, formability, and weldability that defines S235 steel, with an explicit focus on its delivery condition. It is **not a "High Manganese" steel**, and its mechanical properties are not enhanced for low-temperature service beyond the base "JR" level. **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 & Condition Designation:** **S235JRG1** * **S:** Structural Steel. * **235:** Minimum yield strength in MPa (for nominal thickness ≤ 16mm). * **JR:** Base quality designation. Impact tested at **+20°C (Room Temperature)**. * **G1:** Supplementary designation for the **delivery condition**. "G1" specifies the product is supplied in the condition as defined in the standard for hot-rolled products, **typically the as-rolled (AR) condition**. * **Clarification:** The "G1" designation is primarily a formal statement of the standard delivery condition and is often omitted in common trade, where "S235JR" is used interchangeably. It serves to explicitly differentiate from other conditions like normalized (G3) or thermomechanically rolled (G4). * **Clarification on "High Manganese":** This is **incorrect**. S235JRG1 has a standard manganese content for its class (≤1.40%). Its designation is about processing condition, not alloy content. * **Common International Equivalents:** * **ASTM:** **A36** (general purpose equivalent). * **JIS:** **SS400**. * **GB/T:** **Q235B**. **Chemical Composition (Ladle Analysis, % by weight, maximum values):** Standard composition for S235JR. * **Carbon (C):** ≤ **0.17%** * **Manganese (Mn):** ≤ **1.40%** (Standard range). * **Phosphorus (P):** ≤ **0.045%** * **Sulphur (S):** ≤ **0.045%** * **Nitrogen (N):** ≤ **0.014%** (for killed steel). **Physical & Mechanical Properties (for hot-rolled/as-rolled 'G1' condition, thickness ≤ 16mm):** * **Yield Strength (ReH):** ≥ **235 MPa** (Minimum for t ≤ 16mm; decreases with thickness). * **Tensile Strength (Rm):** **360 - 510 MPa**. * **Elongation at Break (A5):** ≥ **26%** (Minimum, longitudinal). * **Impact Energy (KV):** ≥ **27 J at +20°C** (Longitudinal, Charpy V-notch). **No guarantee for lower temperatures.** * **Delivery Condition:** **As-Hot-Rolled**. The microstructure and properties are a direct result of the rolling and cooling process, without subsequent heat treatment. * **Density:** **~7.85 g/cm³**. * **Modulus of Elasticity:** **210 GPa**. **Product Features:** 1. **Standard Base Grade:** Represents the most common and economical form of S235 structural steel. 2. **Excellent Weldability and Formability:** Low carbon equivalent ensures easy welding and good cold bending performance. 3. **As-Rolled Properties:** Offers a good balance of strength and ductility directly from the mill, suitable for the vast majority of general applications not requiring enhanced toughness or special processing. **Typical Applications:** S235JRG1 is used for general structural purposes where no special low-temperature or processing requirements exist. * **General Construction:** Beams, columns, braces, and plates in buildings, warehouses, and light industrial structures in temperate climates. * **Fabrication:** Machine bases, guards, frames, staircases, and handrails. * **Non-Critical Infrastructure:** Fencing, simple supports, and non-load bearing elements. **Available Forms & Processing:** * **Forms:** Hot-rolled sheets, plates, strips, bars, and all standard structural sections. * **Surface:** With mill scale. * **Processing:** Easily cut, welded, drilled, and formed. --- **Critical Note:** The designation **S235JRG1** is technically precise but functionally identical to the commonly used **S235JR**. The "G1" explicitly confirms the as-rolled condition. It is **not suitable for cold climates** (below 0°C service). The term **"High Manganese" is completely erroneous** and should not be associated with this grade. For projects requiring guaranteed toughness at lower temperatures, grades like **S235J2** or **S235J2G3/G4** must be specified. -:- For detailed product information, please contact sales. -: EN S235JRG1 High Manganese, Structural, Hot Rolled, Base Steel Specification Dimensions Size： Diameter 20-1000 mm Length <5815 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 S235JRG1 High Manganese, Structural, Hot Rolled, Base Steel Properties -:- For detailed product information, please contact sales. -:
