A flange—also referred to as a flange plate or rim—is a component used to connect shafts to one another, or, more commonly, to join the ends of pipes. Flanges are also utilized at the inlet and outlet ports of equipment to facilitate connections between two devices—for instance, the flange on a speed reducer. A "flange connection" or "flanged joint" refers to a detachable joint assembly comprising three interconnected elements—a flange, a gasket, and bolts—that together form a sealed structural unit. In the context of piping systems, a "pipe flange" specifically denotes a flange used for plumbing within the installation; when applied to equipment, it refers to the inlet or outlet flange of that specific device. Flanges feature a series of holes through which bolts are inserted to securely fasten the two flanges together, while a gasket placed between the flanges ensures a leak-proof seal. Flanges are broadly categorized into three types: threaded (screw-in) flanges, welded flanges, and clamp-type flanges. Flanges are invariably used in pairs; threaded flanges are suitable for low-pressure piping applications, whereas welded flanges are required for systems operating at pressures exceeding 4 kilograms per square centimeter. A sealing gasket is inserted between the two flange plates, which are then firmly secured using bolts. The thickness of a flange—as well as the specifications of the bolts used to fasten it—vary depending on the specific pressure rating required for the application. When connecting equipment such as water pumps or valves to piping systems, the corresponding connection points on these devices are often manufactured in the shape of a matching flange; this method of attachment is also referred to as a "flange connection." Generally, any connecting component that utilizes bolts to join and seal the perimeters of two flat surfaces—such as the joints in ventilation ducts—is termed a "flange"; such components may collectively be classified as "flange-type parts." However, since such a connection often constitutes merely a *portion* of a larger device—for instance, the interface between a flange and a water pump—it would be inappropriate to classify the entire water pump itself as a "flange-type part." Conversely, smaller components—such as valves—that feature such flanged interfaces may indeed be appropriately categorized as "flange-type parts." -:- For detailed product information, please contact sales. -: EN 1.0036 High Manganese Carbon Steel Flange Product Information -:- For detailed product information, please contact sales. -: EN 1.0036 High Manganese Carbon Steel Flange Synonyms -:- For detailed product information, please contact sales. -:

EN 1.0036 High Manganese Carbon Steel Product Information -:- For detailed product information, please contact sales. -: # **Technical Datasheet: EN 1.0036 High Manganese Carbon Steel** ## **1. PRODUCT OVERVIEW** **EN 1.0036** (also designated as **Fe 360-2** under the older EN 10025 standard and commonly associated with **S235JRG2**) is a **non-alloy, high manganese carbon structural steel** specifically formulated for excellent cold-forming capabilities. Unlike standard mild steels with similar carbon content, 1.0036 features an intentionally elevated **Manganese (Mn) to Carbon (C) ratio**, which significantly enhances its strength, toughness, and work-hardening characteristics without compromising weldability or formability. This steel is a fundamental engineering material prized for its **optimal balance of mechanical properties, ease of fabrication, and cost-effectiveness**. It is supplied in various semi-finished and finished forms (plates, sheets, sections, bars) primarily in the **hot-rolled, normalized, or controlled-rolled condition**. Its primary role is in structural applications where the combination of moderate strength, good ductility, and reliable performance under dynamic loads is required. **Key Characteristics:** - **Enhanced Mn:C Ratio:** Provides better strength and impact toughness than standard low-carbon steels. - **Excellent Cold Formability:** Suitable for bending, rolling, and other forming operations at room temperature. - **Good Weldability:** Can be welded by all common methods without preheating in most thicknesses. - **Cost-Effective Performance:** Delivers superior mechanical properties to basic mild steels at a minimal cost premium. - **Guaranteed Impact Properties:** Supplied with certified Charpy V-notch impact values at room temperature. --- ## **2. CHEMICAL COMPOSITION** **Compliance:** EN 10025-2:2019 (Hot rolled products of structural steels) The chemical composition is carefully controlled to ensure the desired mechanical properties and weldability. The key feature is the elevated manganese content relative to the carbon level. | Element | Minimum (%) | Maximum (%) | Typical (%) | Metallurgical Function | | :--- | :---: | :---: | :---: | :--- | | **Carbon (C)** | — | 0.17 | 0.14 | Provides solid solution strengthening. Kept low to ensure weldability and formability. | | **Manganese (Mn)** | — | 1.40 | 1.20 | **Primary strengthener and toughener.** Enhances hardenability, refines grain structure, and combines with sulfur to form MnS, improving hot workability. The high Mn content relative to C is the defining characteristic. | | **Phosphorus (P)** | — | 0.035 | ≤ 0.025 | Residual element (impurity). Strictly limited to prevent cold shortness (embrittlement). | | **Sulfur (S)** | — | 0.035 | ≤ 0.020 | Residual element. Controlled to form benign MnS inclusions; high levels harm toughness and weldability. | | **Silicon (Si)** | — | 0.55 | 0.30 | Deoxidizer (killed steel). Contributes to strength. | | **Nitrogen (N)** | — | 0.012 | ≤ 0.009 | Residual gas. Controlled to prevent strain aging embrittlement. | | **Copper (Cu)** *Optional* | 0.20 | 0.55 | — | May be specified for enhanced atmospheric corrosion resistance (weathering steel variant). | | **Iron (Fe)** | Balance | — | Balance | Base metal. | **Key Notes on Chemistry:** - The steel is fully **aluminum-killed** (Al typically 0.02-0.06%), ensuring fine grain structure and good surface quality. - The **CEV (Carbon Equivalent Value)** for weldability is low, typically calculated as **CEV = C + Mn/6 ≈ 0.34-0.38%**, indicating excellent weldability without preheating for most common thicknesses. - The **Pcm (Cracking Parameter)** is also very low, further confirming good weldability. --- ## **3.

Detailed Mechanical Property Ranges by Thickness:** *Typical values may exceed minimums.* | Product Thickness (t) | Yield Strength ReH (Typical) | Tensile Strength Rm (Typical) | Elongation A (Typical) | | :--- | :---: | :---: | :---: | | **t ≤ 3 mm** | 260-300 MPa | 400-450 MPa | 28-32% | | **3 mm < t ≤ 16 mm** | 245-285 MPa | 380-430 MPa | 26-30% | | **16 mm < t ≤ 40 mm** | 235-275 MPa | 370-420 MPa | 24-28% | | **40 mm < t ≤ 63 mm** | 225-265 MPa | 360-410 MPa | 22-26% | **Impact Toughness:** The guaranteed **27J at +20°C** makes it suitable for many structural applications in moderate climates. For lower service temperatures, grades like 1.0038 (S235J0) or 1.0116 (S235J2) with impact testing at 0°C or -20°C should be selected. ### **D. Fabrication Properties:** - **Formability:** Excellent. Minimum bending radius (for 90° bend) is typically **0.5 x t** (for t ≤ 3mm) to **1.5 x t** (for t > 10mm) when bending parallel to the rolling direction. - **Machinability:** Good (approximately 50% of free-cutting steel 1212). The relatively low carbon and consistent microstructure allow for stable machining. - **Surface Quality:** Hot-rolled surfaces with mill scale are standard. Pickled and oiled or shot-blasted finishes are available. --- ## **4. HEAT TREATMENT & PROCESSING** EN 1.0036 is generally used in the **as-delivered hot-rolled or normalized condition**. Further heat treatment is not typically required for its intended structural applications. - **Hot-Rolling:** The standard delivery condition. Provides a fine-grained ferrite-pearlite microstructure. - **Normalizing (N):** An optional delivery condition involving reheating to 880-920°C followed by air cooling. This further refines the grain structure, resulting in more uniform and slightly improved mechanical properties, especially in thicker sections. - **Stress Relieving:** If required after severe cold forming or welding of complex structures, heating to 550-650°C, soaking, and slow cooling can relieve internal stresses. - **Hardening/Tempering:** Not applicable or economical for this grade. Its properties are derived from its chemical composition and hot-working process. **Weldability:** **Excellent.** Can be welded by all common processes: SMAW (MMA), GMAW (MIG/MAG), FCAW, SAW, etc. - **Preheating:** Generally not required for thicknesses below ~30-40 mm, depending on joint restraint and ambient temperature. - **Filler Metals:** Electrodes and wires matching or slightly overmatching the strength (e.g., EN ISO 2560-A: E 38 0 R C 12 / AWS A5.1: E7018) are commonly used. - **Post-Weld Heat Treatment:** Usually not necessary. --- ## **5.
