EN S235J2G3C High Manganese, Structural, Hot Rolled, Quality Steel Product Information -:- For detailed product information, please contact sales. -: **Product Name:** EN S235J2G3C Structural Steel for Cold Forming, Hot Rolled, Normalized **Overview:** EN S235J2G3C is a specialized **non-alloy structural steel** that combines three key performance characteristics: **guaranteed low-temperature toughness (-20°C), a normalized microstructure for homogeneity, and optimized chemical composition for superior cold formability.** The "C" suffix explicitly denotes its primary purpose: **steel intended for cold forming**. It is supplied in the hot-rolled and subsequently normalized condition. This grade represents a high-quality, fabrication-friendly option for critical components that require significant cold working and must perform reliably in cold environments. It is **not a "High Manganese" steel**; its defining attributes are its processing condition and formability, not an elevated manganese content. **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 & Designation Decoding:** **S235J2G3C** * **S:** Structural Steel. * **235:** Minimum yield strength in MPa (for thickness ≤ 16mm). * **J2:** Quality designation, guaranteeing impact energy at **-20°C**. * **G3:** Supplementary designation for the **delivery condition: normalized or normalized rolled**. * **C:** Supplementary designation for **steels intended for cold forming**. * **Core Concept:** This is a **specialized, dual-qualified steel**. The "G3C" combination mandates: 1. A normalized state for uniform properties. 2. A chemical composition with tighter limits on carbon, phosphorus, and sulphur specifically to enhance cold formability. * **Clarification:** The term **"High Manganese" is incorrect**. The "C" grade typically has a manganese content comparable to or slightly lower than standard grades to aid formability, not increase strength. **Chemical Composition (Ladle Analysis, % by weight, maximum values per EN 10025-2 for 'C' grades):** Stricter limits than standard S235J2 to prevent cracking during cold work. * **Carbon (C):** ≤ **0.17%** (Often targeted to be on the lower side of this limit). * **Manganese (Mn):** ≤ **1.40%** (Not elevated; may be controlled to a narrower range). * **Phosphorus (P):** ≤ **0.030%** (Tighter than the standard ≤0.035% for J2, reduces cold shortness). * **Sulphur (S):** ≤ **0.030%** (Tighter than the standard ≤0.035% for J2, improves ductility and surface quality for forming). * **Nitrogen (N):** ≤ **0.012%**. * **Note:** The combined reduction of P and S is the critical chemical differentiator that defines its superior cold formability. **Physical & Mechanical Properties (for normalized 'G3' condition, thickness ≤ 16mm):** * **Yield Strength (ReH):** ≥ **235 MPa** (Minimum, thickness-dependent. Normalizing often results in values at the lower end of the range, which is beneficial for cold forming). * **Tensile Strength (Rm):** **360 - 510 MPa**. * **Elongation at Break (A5):** ≥ **26%** (Minimum, typically higher in practice due to the favorable normalized structure and "C" grade chemistry). * **Impact Energy (KV):** **≥ 27 J at -20°C** (Longitudinal, Charpy V-notch). The normalized condition ensures this toughness is consistent through the thickness. * **Cold Formability:** **Excellent.** This is the primary feature. The steel is certified to withstand severe cold deformation (e.g., tight-radius bending, roll-forming, deep drawing) without cracking. Minimum bend radii are typically smaller than for non-"C" grades of the same strength. * **Microstructure:** Uniform, fine-grained ferrite-pearlite structure from normalizing, providing isotropic forming behavior. * **Density:** **~7.85 g/cm³**. **Product Features:** 1. **Exceptional Cold Formability (Primary Feature):** The "C" designation ensures the steel is chemically optimized to withstand demanding cold forming operations without failure, reducing scrap rates in fabrication. 2. **Guaranteed Low-Temperature Toughness:** The **J2** quality provides reliable impact resistance down to **-20°C**, making finished components suitable for cold climate service. 3. **Normalized Homogeneity (G3):** The normalized condition ensures uniform mechanical properties throughout the material, eliminates rolling-induced stresses, and provides predictable, consistent behavior during forming and welding. 4. **Excellent Weldability:** Very low carbon equivalent allows for easy welding with all standard methods. **Typical Applications:** S235J2G3C is specified for complex, cold-formed components that will be used in low-temperature environments. * **Cold-Formed Safety Components:** **Brackets, connectors, and reinforcements** in vehicle chassis or structural frames for use in cold climates. * **Architectural & Construction Elements:** Complex **cold-formed sections for facades, curtain walls, and roofing systems** in cold regions where material toughness is mandated. * **Specialized Storage & Handling:** Critical **cold-rolled profiles for heavy-duty racking systems** in unheated warehouses. * **General Fabrication:** Any component requiring **both a tight cold-formed shape and certified -20°C impact toughness**, such as protective guards, housings, or supports for outdoor machinery. **Available Forms & Processing:** * **Forms:** Most commonly supplied as **normalized plates and hot-rolled strip/sheet** (often in coils), which serve as feedstock for cold-rolling mills. * **Surface:** May be supplied with mill scale from normalizing, or as **pickled and oiled (PO)** for optimal cold forming performance and tool life. * **Processing:** **Uniquely suited for severe cold forming operations followed by welding.** It is the ideal choice when fabrication involves significant bending or rolling prior to assembly. --- **Critical Procurement Note:** The designation **S235J2G3C** is highly specific. Ordering **S235J2G3** (without the C) will deliver normalized steel with -20°C toughness but **not** the optimized chemistry for cold forming, risking cracking during aggressive forming. This is a **premium, application-specific grade**. For projects not involving severe cold work, S235J2 or S235J2G3 may be more economical. **"High Manganese" is a misnomer;** this steel's premium is paid for **enhanced cold formability and guaranteed low-temperature toughness in a normalized state**. Always verify the applicable mechanical property values for the ordered thickness. -:- For detailed product information, please contact sales. -: EN S235J2G3C High Manganese, Structural, Hot Rolled, Quality Steel Specification Dimensions Size： Diameter 20-1000 mm Length <5808 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 S235J2G3C High Manganese, Structural, Hot Rolled, Quality Steel Properties -:- For detailed product information, please contact sales. -:
