Overview** EN 1.1100 (commercially known as **P460NH**) is a normalized, high-strength, micro-alloyed carbon-manganese steel designed specifically for the construction of welded pressure equipment. The "NH" designation indicates that it is **Normalized** and suitable for use at **High** temperatures. By leveraging a precisely controlled combination of higher manganese content and micro-alloying elements like niobium and/or vanadium, this grade achieves significantly higher yield and tensile strengths than standard carbon pressure vessel steels (e.g., P235, P295), while maintaining good weldability and notch toughness. It is a key material for weight-optimized, high-performance pressure vessels operating at elevated temperatures. ### **2. Chemical Composition (Weight %, ladle analysis)** The composition is specified under EN 10028-3:2017 for normalized weldable fine grain steels. The steel is typically fine grain treated (e.g., aluminum killed). | Element | Minimum (%) | Maximum (%) | Notes | |---------|------------|------------|-------| | **Carbon (C)** | - | 0.20 | Controlled for weldability and strength balance. | | **Silicon (Si)** | - | 0.60 | Deoxidizing agent, contributes to strength. | | **Manganese (Mn)** | 1.00 | 1.70 | **Key element.** High Mn provides solid solution strengthening. | | **Phosphorus (P)** | - | 0.025 | Strictly limited to ensure toughness. | | **Sulfur (S)** | - | 0.010 | Very low to improve weldability and hot formability. | | **Aluminum, total (Alt)** | 0.020 | - | For grain refinement (fine grain steel). | | **Nitrogen (N)** | - | 0.020 | Controlled. | | **Niobium (Nb)** | - | 0.05 | **Micro-alloying element.** Added for grain refinement and precipitation strengthening (can be used alone or in combination with V). | | **Vanadium (V)** | - | 0.10 | **Micro-alloying element.** Enhances strength through precipitation hardening. | | **Carbon Equivalent (CEV)*** | - | ~0.45 - 0.50 (calc.) | Indicates weldability; requires proper procedure. | **Note:** The exact combination and limits of Nb, V, and Ti are manufacturer-dependent but comply with the standard's overall requirements. CEV is calculated as per EN 10028-3 (C+Mn/6+(Cr+Mo+V)/5+(Ni+Cu)/15). ### **3. Physical & Mechanical Properties** *Properties are for normalized (N) condition and are thickness-dependent. Values below are typical for plates up to 30mm.* **Mechanical Properties at Room Temperature (min. values per EN 10028-3):** * **Yield Strength (ReH, min):** 460 MPa (for thickness t ≤ 30mm) * **Tensile Strength (Rm):** 550 - 720 MPa * **Elongation (A, min on 5.65√S₀):** 17% (longitudinal, for t ≤ 30mm) * **Impact Energy (KV, min):** * **Test Temperature:** -20°C (for material thickness >12mm, unless otherwise agreed to 0°C or -40°C). * **Minimum Average (Longitudinal):** 40 J * **Minimum Single Value:** 30 J * **Hardness (typical):** 150 - 190 HBW **Physical Properties (Typical):** * **Density:** 7.85 g/cm³ * **Modulus of Elasticity:** 210 GPa * **Poisson's Ratio:** 0.3 * **Thermal Conductivity:** ~ 48 W/m·K (at 20°C) * **Coefficient of Thermal Expansion:** ~ 11.5 x 10⁻⁶ /K (20-100°C) **High-Temperature Properties:** EN 10028-3 specifies minimum yield strength (Rp0.2) values at elevated temperatures (e.g., ~435 MPa at 50°C, ~385 MPa at 100°C, ~325 MPa at 200°C, ~275 MPa at 300°C). ### **4. Key Characteristics** * **High Strength-to-Weight Ratio:** The primary advantage. Enables the design of thinner-walled vessels, reducing weight and material costs for large-scale equipment. * **Fine-Grain Structure:** Achieved through aluminum treatment and normalization, ensuring good toughness and consistent mechanical properties. * **Good Weldability (with precautions):** While the CEV is higher than standard carbon steels, it remains readily weldable using established procedures (pre-heat, controlled heat input, matching low-hydrogen electrodes). Post-weld heat treatment (PWHT) is often recommended for thicker sections. * **Excellent Elevated Temperature Strength:** Specifically designed to retain higher strength at operating temperatures up to approx. 300-350°C, making it suitable for hot process vessels. * **Good Formability:** Suitable for hot and cold forming operations, though higher strength may require more force. ### **5. Product Applications** EN 1.1100 (P460NH) is used in demanding pressure equipment applications where strength and temperature resistance are critical: * **High-Pressure Process Vessels:** Reactors, separators, and scrubbers in petrochemical, chemical, and fertilizer plants. * **Steam Boilers & Heat Exchangers:** Drums, headers, and pressure parts operating at medium to high temperatures and pressures. * **Gas Storage & Transportation:** Spheres and large-capacity storage tanks for industrial gases under pressure. * **Power Generation:** Components in conventional and biomass-fired power plants. * **Offshore & Maritime:** Pressure-containing parts on oil & gas platforms and ships. ### **6. International Standards & Specifications** EN 1.1100 is a European standard grade with direct and approximate international equivalents. | Region | Standard & Designation | Scope / Notes | |--------|----------------------|---------------| | **European Union** | **EN 10028-3:2017** | Flat products for pressure purposes - Part 3: **Weldable fine grain steels, normalized**. **Grade: P460NH**. | | **European Union** | EN 10216-3 / EN 10217-3 | Seamless / Welded tubes for pressure purposes, fine grain steel. | | **International** | **ISO 9328-3** | Technically equivalent to EN 10028-3. Grade: **P460NH**. | | **Germany** | DIN 17155 (Historic) | The predecessor grade was **19Mn5/19Mn6 with micro-alloying**. | | **USA / ASTM** | **ASTM A516/A516M Grade 70** | A common non-identical commercial equivalent with similar strength level and application. **Not normalized by default.** | | **USA / ASTM** | **ASTM A537 Class 2** | A closer normalized equivalent with specified impact properties. | | **Japan** | JIS G3115 SG295 / SG325 | Similar application but generally lower strength class. | ### **7. Available Forms & Processing** * **Standard Forms:** Primarily supplied as **plates and sheets**. Also available as **sections, forgings, and tubes/pipes** to corresponding product standards. * **Condition:** **Normalized (N)**. This is mandatory to achieve the specified fine grain structure and mechanical properties. * **Fabrication:** * **Welding:** Requires qualified procedures. Use low-hydrogen, high-toughness filler metals (e.g., EN ISO 16834-A classified wires/rods). Pre-heat and interpass temperature control are essential. PWHT is common. * **Forming:** Good hot forming properties. Cold forming may require annealing for severe deformations. * **Machining:** Machinability is fair; tougher than lower-strength carbon steels. ### **8. Comparison & Selection Considerations** P460NH is selected over **P295GH/P355NH** when higher design pressures or significant weight savings are required. It offers a cost-effective alternative to **quenched and tempered (QT)** steels (like P500Q/QL1) for many applications where the properties of normalized steel are sufficient. The choice between P460NH and a QT grade depends on design code allowable stresses, required toughness, and fabrication constraints. --- **Disclaimer:** This document provides a technical overview. For design, engineering, and procurement, it is imperative to consult the latest official version of **EN 10028-3**, the manufacturer's material test certificate, and the relevant pressure equipment design codes (e.g., ASME Section VIII, EN 13445). Properties are thickness-dependent and must be verified for the specific product form and size. -:- For detailed product information, please contact sales. -: EN 1.1100 High Manganese Pressure Vessel Carbon Steel Specification Dimensions Size： Diameter 20-1000 mm Length <7381 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 1.1100 High Manganese Pressure Vessel Carbon Steel Properties -:- For detailed product information, please contact sales. -:
