EN 1.0144 Structural, Hot Rolled, Quality Steel, t 200-250 mm Product Information -:- For detailed product information, please contact sales. -: **Product Name:** EN 1.0144 Structural Steel, Hot Rolled, Quality Grade, t=200-250 mm **Overview:** EN 1.0144 is a standard non-alloy quality structural steel grade as specified in the European standard EN 10025-2. This hot-rolled steel is designed for general structural applications where good weldability, formability, and toughness are required. The product is supplied in heavy plates with a thickness range of 200 to 250 mm, making it suitable for large-scale, high-load-bearing components. **Key International Standard:** * **Primary Standard:** EN 10025-2:2019 - Hot rolled products of structural steels - Part 2: Technical delivery conditions for non-alloy structural steels. * **Equivalent/Related Standards:** * **DIN:** DIN S235JR (Historical/legacy designation, closely related) * Note: Specific equivalents in ASTM, JIS, or GB standards would depend on the exact property requirements, but it is broadly comparable to ASTM A36 in terms of application, though chemical limits differ. **Chemical Composition (ladle analysis, % by weight, typical max values):** The composition is defined by the EN 10025-2 standard for quality grade steels. Key elements include: * **Carbon (C):** ≤ 0.17% * **Manganese (Mn):** ≤ 1.40% * **Phosphorus (P):** ≤ 0.045% * **Sulphur (S):** ≤ 0.045% * **Nitrogen (N):** ≤ 0.014% * **Silicon (Si):** Typically ≤ 0.050% (for killed steel, as required for thicker sections) * The low carbon and sulphur content, along with controlled nitrogen, ensure good weldability and cold forming properties. **Physical & Mechanical Properties (at room temperature, typical for t ≤ 250mm):** Properties are guaranteed for the normalized (hot-rolled) delivery condition. * **Yield Strength (ReH):** ≥ 235 MPa (Min. yield strength for thickness ≤ 40mm; for thickness 200-250mm, a reduction in min. yield strength may apply as per standard thickness derogations). * **Tensile Strength (Rm):** 360 - 510 MPa * **Elongation at Break (A5):** ≥ 24% (Minimum, based on standard test piece for thicker plates). * **Impact Energy (KV):** ≥ 27 J at +20°C (Longitudinal, Charpy V-notch test. This is specified for the "JR" quality designation inherent in EN 1.0144). * **Density:** Approximately 7.85 g/cm³. * **Modulus of Elasticity:** ~210 GPa. **Product Features:** * **Good Weldability:** The low carbon equivalent (CET) allows for common welding methods (SMAW, SAW, FCAW, etc.) without pre-heating in most cases, though specific procedures are required for very thick sections. * **Excellent Formability:** Suitable for cold bending and other forming operations. * **Reliable Toughness:** Guaranteed minimum impact energy at room temperature. * **Cost-Effective:** A versatile, economical choice for a wide range of structural applications. **Typical Applications:** This thick-plate product is engineered for heavy-duty structural components, including: * **Heavy Construction:** Base plates, columns, girders, and trusses in industrial buildings, bridges, and high-rise structures. * **Shipbuilding:** Internal structural members, bulkheads, and foundations. * **Offshore & Marine Structures:** Components for jetties, platforms (non-primary), and harbor equipment. * **Heavy Machinery:** Frames, supports, and chassis for mining, material handling, and agricultural equipment. * **Civil Engineering:** Components for tunnels, dams, and large retaining walls. **Available Forms & Sizes:** * **Form:** Hot-rolled steel plates. * **Thickness Range:** 200 mm to 250 mm. * **Width & Length:** As per mill capability and customer order, typically up to several meters in width and length. **Notes:** * For thicknesses over 40mm, the minimum yield and tensile strengths may be subject to agreed reductions as per EN 10025-2. The exact values must be confirmed at the time of enquiry/ordering. * The product is typically supplied in the normalized (hot-rolled) state. Further heat treatment (e.g., stress relieving) can be specified. * Strict quality control during manufacturing ensures internal soundness and homogeneity, which is critical for the performance of such thick sections. * It is essential to consult the mill's technical data sheets for the most precise and batch-specific property guarantees. -:- For detailed product information, please contact sales. -: EN 1.0144 Structural, Hot Rolled, Quality Steel, t 200-250 mm Specification Dimensions Size： Diameter 20-1000 mm Length <5796 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 1.0144 Structural, Hot Rolled, Quality Steel, t 200-250 mm Properties -:- For detailed product information, please contact sales. -:
