EN S235JRG2C High Manganese, Structural, Hot Rolled, Quality Steel Product Information -:- For detailed product information, please contact sales. -: **Product Name:** EN S235JRG2C Structural Steel (Note: Specification Anomaly) **Overview:** The designation **EN S235JRG2C** represents an **anomalous, contradictory, and virtually non-existent specification** within the EN 10025-2 standard. It combines three supplementary designations (J, R, G2, C) that are inherently incompatible for standard procurement. The core contradiction lies in pairing **"G2"** — which indicates material *outside standard mechanical property tables* (for heavy thicknesses, typically >63mm) — with **"C"** — which indicates steel *optimized for cold forming*. Cold forming ("C") is a property highly relevant to thin-to-medium gauge sheet/plate, while "G2" pertains to massive sections where cold forming is not a typical process. This combination is illogical and should not be used in practice. **Key International Standards & Interpretation:** * **Primary Standard:** **EN 10025-2:2019**. * **Designation Deconstruction:** * **S235:** Nominal yield strength class. * **JR:** Base quality, impact tested at **+20°C**. * **G2:** **"Steels for which the specified minimum values of yield strength and tensile strength are not applied."** Used for **non-standard, very heavy thicknesses (e.g., t > 63-150mm+)** where properties must be specially agreed. * **C:** **"Steels intended for cold forming."** Requires tighter limits on P and S (≤0.030% each). * **The Inherent Conflict:** The "C" designation implies a standard, formable product with known properties. The "G2" designation explicitly states that the standard properties do not apply and requires negotiation. A mill cannot guarantee cold-forming performance on a "property-not-guaranteed" heavy forging or ultra-heavy plate. **This combination is not foreseen by the standard for practical application.** **Hypothetical Chemical Composition (If Forced to Interpret):** If a producer were to attempt this, the chemistry would be a hybrid: * **Carbon (C):** ≤ **0.17%** * **Manganese (Mn):** ≤ **1.40%** (Not "High Manganese"). * **Phosphorus (P):** ≤ **0.030%** (Mandatory from "C"). * **Sulphur (S):** ≤ **0.030%** (Mandatory from "C"). * **Silicon (Si):** For killed steel. * **Note:** The low P and S would be beneficial for through-thickness properties in a heavy section, aligning more with the intent of improved soundness than cold forming. **Hypothetical Physical & Mechanical Properties:** **Properties would be entirely subject to agreement.** The "G2" overrides all standard guarantees. * **Yield Strength (ReH):** **Not applicable per standard. To be agreed.** Might be ~215-225 MPa for a very thick section. * **Tensile Strength (Rm):** **Not applicable per standard. To be agreed.** * **Elongation (A5):** **To be agreed.** * **Impact Energy (KV):** Likely **≥ 27 J at +20°C** per JR quality, but test location critical. * **Cold Formability:** **Meaningless for "G2" thicknesses.** The "C" designation becomes functionally irrelevant, as plates >63mm are not cold formed. * **Ultrasonic Testing (UT):** **Mandatory** for such heavy product. **Product Features (Theoretical):** This designation, if used, would likely be an **erroneous attempt to specify a very heavy plate with improved internal cleanliness (low P, S)** rather than a true cold-forming steel. The "C" in this context would be misinterpreted. **Correct Specifications for Intended Applications:** To avoid confusion and ensure correct material supply, use one of the following established designations: 1. **For Cold Forming of Standard Thickness Plate/Sheet (t < 40mm):** * **EN S235JRC** (for as-rolled). * **EN S235JRG1C** (explicitly as-rolled for forming). 2. **For Heavy Thickness Plate (t > 63mm) with Standard Properties:** * **EN S235JRG2** (with explicitly agreed mechanical properties in the order). 3. **For Heavy Thickness Plate (t > 63mm) with Improved Internal Cleanliness** (similar to the *possible* misinterpreted intent of "G2C"): * **EN S235JRG2** with supplementary requirement: **"P ≤ 0.030%, S ≤ 0.030%"** and possibly **"Z-direction quality per EN 10164, class Z25"**. **Conclusion and Critical Recommendation:** **The designation EN S235JRG2C should not be used.** It is a conflicting and nonsensical combination that will cause immediate clarification requests from any competent steel producer and likely lead to supply errors. * It incorrectly suggests cold forming of ultra-heavy plate. * It obscures the fundamental requirement to negotiate mechanical properties for "G2" material. * The term **"High Manganese" is also completely inaccurate**. **Always use clear, standard-compliant designations.** If the requirement is for a thick plate with good through-thickness ductility, specify **EN S235JRG2** with supplementary chemical and Z-quality requirements. For cold forming, specify a **"C" grade without the "G2"** suffix. -:- For detailed product information, please contact sales. -: EN S235JRG2C High Manganese, Structural, Hot Rolled, Quality Steel Specification Dimensions Size： Diameter 20-1000 mm Length <5819 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 S235JRG2C High Manganese, Structural, Hot Rolled, Quality Steel Properties -:- For detailed product information, please contact sales. -:
