Overview** EN 1.0112 is a non-alloy, carbon-manganese steel specifically designed and normalized for the construction of pressure vessels and boilers. Characterized by its relatively higher manganese content, it offers an improved combination of yield strength and good weldability compared to standard carbon steels. This grade is primarily supplied in normalized condition to ensure a uniform microstructure, providing reliable mechanical properties essential for safety-critical applications involving pressure containment. ### **2. Chemical Composition (Weight %, ladle analysis)** The composition is specified under the EN 10028-2 standard for flat products for pressure purposes. | Element | Minimum (%) | Maximum (%) | Notes | |---------|------------|------------|-------| | **Carbon (C)** | - | 0.16 | Low carbon for weldability. | | **Silicon (Si)** | - | 0.40 | Typically used for deoxidation. | | **Manganese (Mn)** | 1.00 | 1.60 | **High Mn** key for solid solution strengthening. | | **Phosphorus (P)** | - | 0.025 | Low to ensure toughness. | | **Sulfur (S)** | - | 0.015 | Low to improve hot formability. | | **Aluminum (Al)** | ≥ 0.020 (or min N content fixed) | - | Grain refinement, typically Al-killed. | | **Nitrogen (N)** | - | 0.012 | Controlled to prevent aging. | **Material Designation:** * **EN Number:** 1.0112 * **EN Name:** P295GH * **Old German Designation:** Similar to HII (19Mn6). * **Note:** P295GH is the common commercial name under the EN 10028-2 standard, where "P" stands for pressure purposes, "295" indicates the minimum yield strength in MPa at room temperature for thicknesses ≤16mm, "G" for manganese content, and "H" for high-temperature property values. ### **3. Physical & Mechanical Properties** *Properties are for normalized material and are thickness-dependent. Values below are typical for plates up to 16mm.* **Mechanical Properties at Room Temperature:** * **Yield Strength (ReH, min):** 295 MPa (for t ≤ 16mm) * **Tensile Strength (Rm):** 450 - 600 MPa * **Elongation (A, min on 5.65√S₀):** 22% (longitudinal, thickness-dependent) * **Impact Energy (KV, min):** * **Longitudinal:** 40 J at -20°C (27 J required by standard for P295GH at 0°C). * **Transverse:** Typically specified, values may be lower. * **Hardness (typical):** 130 - 170 HBW **Physical Properties (Typical):** * **Density:** 7.85 g/cm³ * **Modulus of Elasticity:** 210 GPa * **Poisson's Ratio:** 0.3 * **Thermal Conductivity:** ~ 50 W/m·K (at 20°C) * **Coefficient of Thermal Expansion:** ~ 11 x 10⁻⁶ /K (20-100°C) **High-Temperature Properties:** EN 10028-2 provides minimum yield strength values at elevated temperatures (e.g., approximately 240 MPa at 200°C, 215 MPa at 250°C). ### **4. Key Characteristics** * **Balanced Strength & Ductility:** The higher manganese content (1.0-1.6%) provides solid solution strengthening, achieving higher yield strength than standard carbon steels (like P235GH) while maintaining good ductility. * **Good Weldability:** Low carbon equivalent (CEV typically ~0.35-0.40) allows for excellent weldability using all common methods (SMAW, GMAW, SAW) without pre-heat for most thicknesses, though proper procedures must be followed. * **Good Formability:** Suitable for cold bending, rolling, and other forming operations. * **Normalized Condition:** Supplied in this state to ensure grain refinement, homogeneity, and consistent mechanical properties throughout the section. * **Cost-Effective:** Provides a performance upgrade over basic carbon grades without the cost of low-alloy steels. ### **5. Product Applications** EN 1.0112 (P295GH) is a workhorse material in pressure equipment for moderate service conditions: * **Pressure Vessels:** Storage tanks (for air, water, oil), columns, reactors, separators, and heat exchangers operating at low to medium pressures and temperatures. * **Boiler Components:** Shells, drums, and other pressurized parts in steam and hot water boilers. * **Industrial Plumbing & Piping:** Large-diameter pressure piping and headers. * **Structural Components in Process Plants:** Where pressure containment is integrated with structural support. * **Cryogenic Applications:** With appropriate impact toughness verification, it can be used for certain sub-zero applications down to -20°C or lower. ### **6. International Standards & Specifications** EN 1.0112 is primarily governed by European (EN) standards but has equivalents in other major systems. | Region | Standard & Designation | Scope / Notes | |--------|----------------------|---------------| | **European Union** | **EN 10028-2:2017** | Flat products for pressure purposes - Part 2: Non-alloy and alloy steels with specified elevated temperature properties. **Grade: P295GH**. | | **European Union** | EN 10216-2 | Seamless tubes for pressure purposes. | | **European Union** | EN 10217-2 | Welded tubes for pressure purposes. | | **Germany** | DIN 17155 (Withdrawn) | Former standard, grade **HII (19Mn6)** is a close predecessor. | | **International** | **ISO 9328-2** | Identical adoption as EN 10028-2. Grade: **P295GH**. | | **USA / ASTM** | **ASTM A516/A516M** | Grade 70 is a common non-identical equivalent, offering similar strength and application. | | **Japan** | JIS G3115 | Grade SB450 has comparable properties. | **Important Notes on Standards:** * Material must be ordered and certified to the specific product standard (e.g., EN 10028-2 for plates). * Supplementary requirements (e.g., enhanced impact testing, NDT) can be specified. ### **7. Available Forms & Processing** * **Standard Forms:** Primarily supplied as **plates, sheets, and strips**. Also available as **seamless and welded tubes/pipes** (to EN 10216-2/EN 10217-2). * **Condition:** **Normalized (N)**. Quenched and tempered (QT) condition may be available for special requirements but is not standard for this grade. * **Fabrication:** Excellent for **welding** (use matching filler metals like EN ISO 14341-A G 42 4 M21 4Si1), **cutting** (plasma, flame, laser), **machining**, and **cold forming**. ### **8. Comparison & Selection Considerations** EN 1.0112/P295GH is a mid-range pressure vessel steel. It is selected over **P235GH** when higher strength is needed to reduce wall thickness/weight. It is preferred over higher-strength low-alloy steels (like **P355** grades) when cost and maximum weldability are primary drivers for applications within its strength and temperature limits. --- **Disclaimer:** This datasheet provides general information. For design, engineering, and procurement, always refer to the latest official version of the relevant material standard (EN 10028-2), the manufacturer's test certificates, and applicable pressure equipment directives (e.g., EU PED 2014/68/EU).
