EN SPH235 High Manganese Pressure Vessel Carbon Steel Product Information -:- For detailed product information, please contact sales. -: # **Product Name:** EN S235 Pressure Vessel Steel Plate (Hot Rolled) **Overview** EN S235, in the context of pressure vessels, is a **non-alloy carbon-manganese steel** specifically designated for welded pressure equipment. It is a **general-purpose steel for pressure purposes**, offering a balance of adequate strength, good weldability, and formability at an economical cost. The **"SPH" prefix is not a standard EN designation**; it may be a proprietary steelmaker's designation or a project-specific code. The correct standardized designation for this quality of pressure vessel steel would typically be **P235GH** (for plates) under EN 10028-2. This material is suitable for the construction of pressure vessels, boilers, and storage tanks operating at moderate temperatures and pressures. **Key International Standards & Clarification** * **Primary Standard:** **EN 10028-2:2017** - Flat products made of steels for pressure purposes - Part 2: Non-alloy and alloy steels with specified elevated temperature properties. * The correct equivalent grade for S235 quality is **P235GH**. * **Designation Decoding (P235GH):** * **P:** Steel for pressure purposes. * **235:** Minimum specified yield strength (ReH) in MPa at room temperature for thicknesses ≤ 16mm. * **G:** Indicates fine grain practice (often achieved by aluminum treatment). * **H:** Indicates suitability for use at elevated temperatures (property values specified up to ~300°C). * **Interpretation of "SPH235":** This appears to be a **non-standard combination**. "S" typically denotes structural steel (EN 10025), "P" denotes pressure vessel steel (EN 10028). "SPH" could be a historical or mill-specific code. **For procurement and compliance, the standardized designation must be used.** * **Clarification on "High Manganese":** This is a **mischaracterization**. As a general-purpose pressure vessel steel, its manganese content is standard (typically ≤1.40%) and not elevated or "high" in a technical sense. Its application defines it as a pressure vessel steel, not its alloy content. **Chemical Composition (Ladle Analysis, % by weight, typical for P235GH per EN 10028-2)** * **Carbon (C):** ≤ **0.16%** * **Manganese (Mn):** ≤ **1.40%** * **Phosphorus (P):** ≤ **0.025%** * **Sulphur (S):** ≤ **0.015%** * **Silicon (Si):** ≤ **0.35%** * **Aluminum (Alt):** ≥ **0.020%** (for fine grain practice) * **Nitrogen (N):** ≤ **0.012%** **Physical & Mechanical Properties (for hot-rolled/normalized condition, thickness ≤ 16mm)** * **Yield Strength (ReH) at 20°C:** ≥ **235 MPa** * **Tensile Strength (Rm):** **360 - 510 MPa** * **Elongation (A):** ≥ **25%** * **Impact Energy:** Values are tested and reported (e.g., at 0°C or +20°C). For guaranteed low-temperature toughness, subgrades like **P235NL** (impact tested at -50°C) must be specified. * **Elevated Temperature Yield Strength:** Guaranteed minimum values are provided in the standard for temperatures up to **300°C**. * **Ultrasonic Testing (UT):** Plates are typically subjected to mandatory non-destructive testing per **EN 10160** to ensure internal soundness. **Product Features** 1. **Pressure Purpose Certified:** Manufactured and tested under strict quality regimes specific to pressure equipment, ensuring higher homogeneity and traceability. 2. **Good Weldability:** Low carbon equivalent allows for reliable welding with common processes. Post-weld heat treatment (PWHT) is often applied for stress relief. 3. **Fine Grain Practice:** Ensures better toughness and more uniform properties. 4. **Economical for Moderate Service:** The standard choice for many static pressure vessels in non-corrosive and non-cryogenic services. **Typical Applications** * **Class I & II Pressure Vessels:** Air receivers, low-pressure storage tanks, heat exchanger shells (non-firing), and process vessels in chemical, food, and beverage industries. * **Boiler Components:** Non-firing parts such as feedwater tanks, deaerators, and economizer casings. * **General Pressure Equipment:** Where design conditions (pressure, temperature) are within the moderate capability of this grade. **Available Forms & Quality Supplements** * **Forms:** Hot-rolled plates. * **Delivery Condition:** Typically supplied in the normalized (N) condition. * **Mandatory Certification:** Supplied with a **Inspection Certificate 3.1 per EN 10204**, which is mandatory for pressure equipment under the Pressure Equipment Directive (PED). --- **Critical Procurement Note** 1. **Use Standard Designation:** Do not use "SPH235". For general pressure vessel plate, specify **EN 10028-2 P235GH**. If low-temperature impact toughness is required, specify the appropriate subgrade (e.g., **P235NL** for -50°C). 2. **Regulatory Compliance:** Material for pressure equipment in Europe must comply with the **Pressure Equipment Directive (PED)** and carry CE marking. The EN 10204 3.1 certificate is a key part of this. 3. **Temperature Limits:** Confirm the suitability of the grade's elevated temperature properties for the maximum design temperature. 4. **Not "High Manganese":** This is not an accurate or useful descriptor for this material. -:- For detailed product information, please contact sales. -: EN SPH235 High Manganese Pressure Vessel Carbon Steel Specification Dimensions Size： Diameter 20-1000 mm Length <5843 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 SPH235 High Manganese Pressure Vessel Carbon Steel Properties -:- For detailed product information, please contact sales. -:
