EN 1.0533 High Manganese, Structural, Hot Rolled, Quality Steel Product Information -:- For detailed product information, please contact sales. -: **Product Name:** EN 1.0533 Structural Steel, Hot Rolled, Quality Grade **Overview:** EN 1.0533 is a **high manganese, non-alloy structural quality steel** primarily used in applications where a combination of good strength and enhanced toughness is required. This grade is defined by its higher manganese content relative to standard structural steels, which provides increased hardenability and tensile strength without the need for significant alloying additions. It is a versatile engineering steel, suitable for a wide range of applications involving forming, machining, and welding, and 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:** Under the standard, EN 1.0533 corresponds to steel grade **S275**. Its specific chemical composition (high Mn) designates it within this strength class. * **Quality Designation:** The standard offers different toughness quality levels: JR, J0, J2, K2. The specific quality (e.g., **S275J0** or **S275J2**) must be explicitly ordered based on the required impact test temperature. * **Equivalents:** * **ASTM:** A570 Grade 40 (approximate strength equivalent). * **JIS:** SS400 (general comparison, not exact). * **GB/T:** Q275B (approximate equivalent). **Chemical Composition (Ladle Analysis, % by weight, maximum or specified range):** The defining characteristic is the elevated manganese (Mn) content, which is significantly higher than in standard S275 grades. * **Carbon (C):** ≤ 0.21% * **Manganese (Mn):** **1.50% max.** *(Key differentiator)* * For thicknesses ≤ 16 mm: Min. typically 0.80% - 1.50% * For thicker sections, a minimum Mn content (e.g., ≥ 1.00% for t > 40mm) ensures the "high manganese" properties are maintained. * **Phosphorus (P):** ≤ 0.040% * **Sulphur (S):** ≤ 0.040% * **Nitrogen (N):** ≤ 0.014% * **Silicon (Si):** ≤ 0.040% (for killed steel, common in thicker plates and higher qualities). * **Carbon Equivalent (CEV):** Typically in the range of 0.35-0.45%, important for assessing weldability. **Physical & Mechanical Properties (for hot-rolled condition, typical for thicknesses ≤ 16mm):** * **Yield Strength (ReH):** **≥ 275 MPa** (Minimum yield strength for nominal thickness ≤ 40mm). * **Tensile Strength (Rm):** **410 - 560 MPa**. * **Elongation at Break (A5):** **≥ 22%** (Minimum, longitudinal test piece). * **Impact Energy (KV):** Varies by ordered quality designation: * **S275JR:** ≥ 27 J at **+20°C** * **S275J0:** ≥ 27 J at **0°C** *(Commonly specified for general engineering)* * **S275J2:** ≥ 27 J at **-20°C** (For colder environments) * (Tested longitudinally, Charpy V-notch). * **Density:** Approximately **7.85 g/cm³**. * **Modulus of Elasticity:** **~210 GPa**. * **Poisson's Ratio:** **~0.3**. **Product Features:** 1. **Enhanced Strength & Toughness:** The high manganese content provides better hardenability, resulting in a favorable combination of yield/tensile strength and impact toughness compared to standard S235 or basic S275 grades. 2. **Good Weldability:** The controlled carbon content and carbon equivalent allow for good weldability using common methods (SMAW, MAG, SAW). Pre-heating recommendations should be followed for thicker sections and restrained joints. 3. **Excellent Formability:** Suitable for cold bending, rolling, and stamping operations due to its balanced composition. 4. **Machinability:** Offers fair to good machinability in its hot-rolled state. 5. **Cost-Effective Performance:** Provides a performance upgrade over mild steels without the cost associated with low-alloy high-strength steels. **Typical Applications:** EN 1.0533 (S275) is widely used in general mechanical engineering and structural components requiring higher strength than mild steel: * **General Construction:** Girders, beams, columns, and brackets in industrial buildings and warehouses. * **Heavy Vehicle Manufacturing:** Chassis components, trailer parts, dump truck bodies, and lifting equipment frames. * **Material Handling:** Conveyor system structures, crane runways, and heavy-duty shelving/support frames. * **Mining & Agricultural Equipment:** Structural parts, buckets, supports, and linkages. * **General Fabrication & Machinery:** Base plates, machine frames, gears, shafts (for less demanding applications), and various stressed components. **Available Forms & Processing:** * **Forms:** Hot-rolled sheets, plates, strips, bars (round, flat, square), and structural sections (angles, channels). * **Surface:** Typically supplied with mill scale. Can be shot blasted or pickled upon request. * **Processing:** Easily cut (laser, plasma, shear), welded, formed, and machined. --- **Important Note:** The mechanical properties, particularly yield strength and impact energy, are thickness-dependent. For plates and sections above 40mm in thickness, the minimum guaranteed values may be reduced as per the standard's derogations. The required **quality designation (JR, J0, J2)** and any supplementary requirements (e.g., ultrasonic testing) must be clearly stated in the purchase order.
