EN SA355J2G3 High Manganese, Structural, Hot Rolled, Quality Steel Product Information -:- For detailed product information, please contact sales. -: # **Product Name:** EN S355J2G3 Structural Steel, Normalized, Quality Grade (Note: Corrected Designation) **Overview** **EN SA355J2G3 is a non-standard designation.** The correct and standard designation for this material is **EN S355J2G3** (or **S355J2+N**), as defined in EN 10025-3. It is a **non-alloy, fine-grained structural quality steel** supplied in the **normalized condition (G3/N)** with **guaranteed impact toughness at -20°C (J2)**. The "A" prefix in the requested designation ("SA") is atypical and likely erroneous; it may be a historical carryover, a project-specific code, or a misinterpretation. This grade is engineered for critical applications where a homogeneous, stress-relieved microstructure and reliable low-temperature performance are essential. It is **not a "High Manganese" steel**; its properties are derived from fine grain practice and heat treatment. **Key International Standards & Correction** * **Primary Standard:** **EN 10025-3:2019** - Hot rolled products of structural steels - Part 3: Technical delivery conditions for normalized/normalized rolled weldable fine grain structural steels. * **Correct Standard Designation:** **S355J2G3** or **S355J2+N** * **S:** Structural Steel. * **355:** Minimum yield strength (ReH) in MPa for thickness ≤ 16 mm. * **J2:** Quality designation for impact testing at **-20°C**. * **G3/N:** Delivery condition: **Normalized**. * **Interpretation of "SA" Prefix:** If encountered, "SA" could ambiguously imply "Steel, Alloy" (unlikely as it's non-alloy) or, more plausibly, denote a **project-specific or purchaser's supplemental requirement** (e.g., additional testing, restricted chemistry). **For procurement, the standard designation "S355J2G3" must be used and clarified with the supplier if "SA" appears on legacy drawings.** * **Clarification on "High Manganese":** This is **incorrect**. The manganese content is standard for fine-grained S355 steels. The key features are its **normalized delivery condition and guaranteed -20°C toughness**. **Chemical Composition (Ladle Analysis, % by weight, max. values per EN 10025-3 for S355J2)** * **Carbon (C):** ≤ **0.18%** * **Manganese (Mn):** ≤ **1.60%** * **Phosphorus (P):** ≤ **0.030%** * **Sulphur (S):** ≤ **0.025%** * **Silicon (Si):** ≤ **0.55%** * **Aluminum (Alt):** ≥ **0.020%** (for grain refinement) * **Nitrogen (N):** ≤ **0.015%** * **Carbon Equivalent (CEV):** ~0.38-0.42% **Physical & Mechanical Properties (for normalized condition, thickness ≤ 16mm)** * **Yield Strength (ReH):** ≥ **355 MPa** * **Tensile Strength (Rm):** **470 - 630 MPa** * **Elongation (A5):** ≥ **21%** * **Impact Energy (KV):** **≥ 27 J at -20°C** (Longitudinal) * **Fine Grain Size:** ≥ **6** (ASTM scale, EN ISO 643) * **Density:** **~7.85 g/cm³** * **Modulus of Elasticity:** **210 GPa** **Product Features** 1. **Homogeneous Normalized Structure:** Provides uniform properties, relieved internal stresses, and predictable fabrication behavior. 2. **Guaranteed Low-Temperature Toughness:** Suitable for dynamically loaded structures in environments down to **-20°C**. 3. **Good Weldability:** The normalized condition offers a stable base for welding. **Typical Applications** * Critical bridge components * Offshore platform secondary structures * Heavy welded machinery frames for cold climates **Available Forms & Processing** * **Forms:** Normalized plates and sections. * **Processing:** Suitable for cutting, welding, and machining. --- **Critical Procurement Note** * **Use Correct Designation:** Specify **"EN 10025-3 S355J2G3"**. If "SA355J2G3" is mandated by a legacy specification, obtain written clarification on any special requirements it entails. * **Thickness-Strength:** Properties are thickness-dependent; refer to EN 10025-3 tables. * **Not "High Manganese":** Discontinue use of this term. -:- For detailed product information, please contact sales. -: EN SA355J2G3 High Manganese, Structural, Hot Rolled, Quality Steel Specification Dimensions Size： Diameter 20-1000 mm Length <5842 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 SA355J2G3 High Manganese, Structural, Hot Rolled, Quality Steel Properties -:- For detailed product information, please contact sales. -:
