EN 1.0145 High Manganese, Structural, Hot Rolled, Quality Steel Product Information -:- For detailed product information, please contact sales. -: ### **Product Name:** EN 1.0145 High Manganese Steel, Hot Rolled, Quality Structural Steel #### **Overview** EN 1.0145 is a **non-alloy, high-manganese quality structural steel** defined by the European standard EN 10025-2. The "high manganese" designation distinguishes it from other standard grades (like 1.0144/S235) by having a higher guaranteed manganese content relative to its carbon level. This composition enhances strength, hardenability, and toughness, making it particularly suitable for components requiring better mechanical performance than standard mild steel, while maintaining good weldability and formability. It is supplied in the hot-rolled condition. #### **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:** Within this standard, the chemical composition of EN 1.0145 corresponds to the steel grade **S275**. * **Quality Designation:** The standard offers different quality levels (JR, J0, J2, K2). EN 1.0145 is typically associated with the **J0** quality (impact tested at 0°C), but the specific quality (JR, J0, J2) must be specified when ordering based on application requirements. * **Comparable Standards:** * **ASTM:** A570 Grade 40 or A36 (with similar strength, but chemical composition differs). * **JIS:** SS400 (general comparison). * **GB/T:** Q275 (approximate equivalent). #### **Chemical Composition (Ladle Analysis, % by weight, max. unless stated as range)** The key feature is the elevated manganese-to-carbon ratio. * **Carbon (C):** ≤ 0.21% * **Manganese (Mn):** ≤ 1.50% * For thicknesses ≤ 16 mm: Min. 0.80% - 1.50% * For thicknesses > 16 mm - 40 mm: Min. 0.90% - 1.50% * For thicknesses > 40 mm - 63 mm: Min. 1.00% - 1.50% (Note: Specific min. values ensure the "high manganese" characteristic.) * **Phosphorus (P):** ≤ 0.040% * **Sulphur (S):** ≤ 0.040% * **Nitrogen (N):** ≤ 0.014% * **Silicon (Si):** ≤ 0.040% (for killed steel, required for thicker sections and certain qualities) #### **Physical & Mechanical Properties (for hot-rolled condition, typical for t ≤ 16mm)** Properties are thickness-dependent. Values decrease slightly with increasing thickness. * **Yield Strength (ReH):** ≥ 275 MPa (Min. for nominal thickness ≤ 40mm). * **Tensile Strength (Rm):** 410 - 560 MPa. * **Elongation at Break (A5):** ≥ 22% (Minimum, based on longitudinal test piece). * **Impact Energy (KV):** * **Quality JR:** ≥ 27 J at +20°C * **Quality J0:** ≥ 27 J at 0°C *(Most common for EN 1.0145)* * Quality J2: ≥ 27 J at -20°C (optional, must be specified) (Tested longitudinally, Charpy V-notch). * **Density:** ~7.85 g/cm³. * **Modulus of Elasticity:** ~210 GPa. * **Poisson's Ratio:** ~0.3. #### **Product Features** 1. **Enhanced Strength:** Higher minimum yield (275 MPa) and tensile strength compared to S235 grades (1.0144), allowing for lighter or stronger designs. 2. **Improved Toughness:** The high manganese content refines the grain structure, contributing to better impact resistance, especially in colder environments (when J0 or J2 quality is ordered). 3. **Good Weldability:** Despite higher strength, the controlled carbon content and carbon equivalent (typically low) allow for good weldability using all common methods. Pre-heating may be required for thicker sections. 4. **Good Formability:** Suitable for cold bending, rolling, and other forming operations. 5. **Cost-Effective Upgrade:** Provides a better performance-to-cost ratio than alloy steels for many applications where standard S235 is insufficient. #### **Typical Applications** EN 1.0145 (S275) is widely used in general and heavy engineering structures where higher load-bearing capacity is needed: * **Structural Construction:** Beams, columns, trusses, and brackets in industrial buildings, warehouses, and medium-span bridges. * **Heavy Vehicle & Transportation:** Chassis frames, trailer undercarriages, railway wagon components, and crane booms. * **Material Handling:** Forklift masts, conveyor system supports, and heavy-duty storage racking. * **Mining & Agricultural Machinery:** Structural parts, buckets, and supports requiring higher abrasion resistance and toughness. * **General Fabrication:** Base plates, frames, and machinery beds where S235 strength is inadequate. #### **Available Forms & Processing** * **Forms:** Hot-rolled sheets, plates, strips, bars, and structural sections (beams, channels, angles). * **Surface Condition:** Usually with mill scale (black). Can be shot blasted or pickled upon request. * **Processing:** Readily suited for cutting (plasma, laser, oxy-fuel), welding, machining, and forming. --- **Important Note:** For critical applications, especially with thicknesses above 40mm or in sub-zero service temperatures, engineers must consult the full EN 10025-2 standard for precise property guarantees (thickness derogations) and specify the required **quality designation (JR/J0/J2)** and any additional testing (e.g., ultrasonic testing for internal soundness) in the purchase order.
