EN 1.0570 High Manganese, Quality Steel Flange

1,We Manufacturing processes are primarily classified into four types: 1:Forging, 2:Casting, 3:Cutting, 4:Rolling. 2,We can manufacture in accordance with these standards. Standards: GB Series (Chinese Standards), JB Series (Machinery Standards), HG Series (Chemical Industry Standards), ASME B16.5 (American Standards), BS4504 (British Standards), DIN (German Standards), and JIS (Japanese Standards). Internationally, there are two primary systems of pipe flange standards: the European system, represented by the German DIN standards (including those of the former Soviet Union), and the American system, represented by the US ANSI pipe flange standards. Other common standards include: the Chinese Ministry of Machinery Industry standards (JB series), the Ministry of Chemical Industry standards (HG series), the Chinese National Standard *GB/T 9112–9124-2010 Steel Pipe Flanges*, as well as US standards (ASME B16.5), British standards (BS4504), German standards (DIN), Japanese standards (JIS), and marine standards (CBM), among others. The nominal pressure ratings for the PN series are designated by "PN" and comprise the following nine levels: PN2.5, PN6, PN10, PN16, PN25, PN40, PN63, PN100, and PN160. The nominal pressure ratings for the Class series are designated by "Class" and comprise the following six levels: Class150, Class300, Class600, Class900, Class1500, and Class2500. Flange Classification 1. **According to Chemical Industry Standards:** Flanges are classified as follows: Plate Flat Welding Flange (PL), Necked Flat Welding Flange (SO), Necked Butt Welding Flange (WN), Integral Flange (IF), Socket Welding Flange (SW), Threaded Flange (Th), Butt Welding Ring Loose Flange (PJ/SE), Blind Flange (BL), Flat Welding Ring Loose Flange (PJ/PJ), and Lined Blind Flange (BL(s)). 2. **According to Petrochemical (SH) Industry Standards:** Flanges are classified as follows: Threaded Flange (PL), Butt Welding Flange (WN), Flat Welding Flange (SO), Socket Welding Flange (SW), Loose Flange (LJ), and Blind Flange (no specific designation). 3. **According to Machinery (JB) Industry Standards:** Flanges are classified as follows: Integral Flange, Butt Welding Flange, Plate Flat Welding Flange, Butt Welding Ring Plate Loose Flange, Flat Welding Ring Plate Loose Flange, Lap Joint Ring Plate Loose Flange, and Blind Flange. 4. **According to Connection Method/Type:** Flanges are classified as follows: Plate Flat Welding Flange, Necked Flat Welding Flange, Necked Butt Welding Flange, Socket Welding Flange, Threaded Flange, Blind Flange, Necked Butt Welding Ring Loose Flange, Flat Welding Ring Loose Flange, Ring-Type Joint (RTJ) Flange and Blind Flange, Large-Diameter Plate Flange, Large-Diameter High-Neck Flange, Figure-8 Blind Plate, Butt Welding Ring Loose Flange, etc. 5. **According to the Component Being Connected:** Flanges can be classified into Vessel Flanges and Pipe Flanges. 6. **According to Structural Type:** Flanges include Integral Flanges, Threaded Flanges, Flat Welding Flanges, Butt Welding Flanges, Lap Joint (Loose/Swivel) Flanges, and Blind Flanges. 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 1.0570 High Manganese, Structural, Hot Rolled, Quality Steel Flange Product Information -:- For detailed product information, please contact sales. -: EN 1.0570 High Manganese, Structural, Hot Rolled, Quality Steel Flange Synonyms -:- For detailed product information, please contact sales. -:

EN 1.0570 High Manganese, Structural, Hot Rolled, Quality Steel Product Information -:- For detailed product information, please contact sales. -: **Product Name:** EN 1.0570 (S355) Structural Steel, Hot Rolled, Quality Grade **Overview:** EN 1.0570 is a **high-manganese, non-alloy structural quality steel** designed for applications demanding superior strength and toughness compared to S275 grades. It is defined under the primary European standard for structural steels and corresponds to the **S355** strength class. The "high manganese" specification indicates an intentionally elevated manganese content, which significantly enhances the steel's strength, hardenability, and impact toughness without moving into low-alloy classifications. This grade represents an optimal balance of performance, weldability, and cost for demanding structural applications and is supplied in the hot-rolled condition. **Key International Standards:** * **Primary Standard:** **EN 10025-2:2019** - Hot rolled products of structural steels - Part 2: Technical delivery conditions for non-alloy structural steels. * **Grade Designation:** The material number 1.0570 refers specifically to a **high-manganese variant within the S355 grade**. * **Quality Designation:** The standard offers several toughness qualities. For this grade, the most common and relevant specifications are: * **S355J0:** Impact tested at **0°C**. * **S355J2:** Impact tested at **-20°C**. * **S355K2:** Impact tested at **-20°C** with additional requirements for fine grain practice and higher toughness. The required quality (e.g., **S355J2**) must be explicitly ordered. * **Equivalents & Comparisons:** * **ASTM:** **ASTM A572 Grade 50** is a close mechanical equivalent (min. yield 345 MPa/50 ksi), though chemistry differs. * **JIS:** SM490A/B/C. * **GB/T:** Q355B/C/D (China's direct equivalent to S355, with matching quality grades). * **ISO:** ISO 630-2:2021 (Structural steels – Part 2: Technical delivery conditions for hot-rolled structural steel products). **Chemical Composition (Ladle Analysis, % by weight, typical maximum values or range):** The higher Mn and controlled C define its performance. * **Carbon (C):** ≤ **0.22%** (Content is controlled to balance strength and weldability). * **Manganese (Mn):** **≤ 1.60%** (Key feature: This elevated upper limit distinguishes it from standard S355 compositions, contributing to strength and hardenability). * For thicknesses > 40 mm, a minimum Mn content (e.g., ≥ 1.00% to 1.20%) is typically required. * **Phosphorus (P):** ≤ **0.035%**. * **Sulphur (S):** ≤ **0.035%**. * **Nitrogen (N):** ≤ **0.018%** (lower than in some grades for improved toughness). * **Silicon (Si):** ≤ **0.55%**. * **Carbon Equivalent (CET or CEV):** Typically in the range of **0.40 - 0.45%**. This is a critical parameter for welding procedure development. **Physical & Mechanical Properties (for hot-rolled condition, typical for thicknesses ≤ 16 mm):** * **Yield Strength (ReH):** ≥ **355 MPa** (Minimum for thickness ≤ 16 mm; decreases with increasing thickness per standard tables). * **Tensile Strength (Rm):** **470 - 630 MPa**. * **Elongation at Break (A5):** ≥ **21%** (Minimum, for longitudinal test piece). * **Impact Energy (KV):** Varies by ordered quality designation (Longitudinal, Charpy V-notch): * **S355J0:** ≥ **27 J at 0°C**. * **S355J2:** ≥ **27 J at -20°C** (Common for outdoor structures in temperate climates). * **S355K2:** ≥ **40 J at -20°C** (For critical applications with higher toughness demand). * **Density:** **~7.85 g/cm³**. * **Modulus of Elasticity:** **210 GPa**. * **Poisson's Ratio:** **0.3**. * **Shear Modulus:** **~81 GPa**. **Product Features:** 1. **High Strength-to-Weight Ratio:** The 355 MPa minimum yield strength allows for lighter, more efficient structural designs compared to S235/S275 steels, reducing material costs and weight. 2. **Excellent Toughness:** The combination of high manganese and controlled processing (often fine-grain practice for J2/K2) ensures good impact resistance at low temperatures, making it suitable for dynamic and low-temperature service. 3. **Good Weldability (with Procedure):** Weldable with all common methods. However, due to the higher carbon equivalent compared to S235, it requires more careful control of welding parameters, pre-heating (especially for thicker sections and restrained joints), and heat input to avoid hydrogen-induced cracking (HIC). 4. **Favorable Formability & Machinability:** Can be cold formed and machined, though power requirements are higher than for lower-strength steels. **Typical Applications:** EN 1.0570 (S355) is one of the most widely used high-strength structural steels in Europe. * **Heavy Construction:** Primary beams, columns, and trusses in **industrial halls, warehouses, high-rise buildings, and bridges**. * **Crane & Lifting Equipment:** Main booms, jibs, and support structures for mobile, tower, and gantry cranes. * **Offshore & Marine:** Components for **harbor structures, inland waterway vessels, and secondary structures on offshore platforms**. * **Heavy Vehicle & Transportation:** Chassis for **trucks, trailers, railway freight cars, and mining trucks**. * **Energy & Heavy Machinery:** Support structures for **power plants, wind turbine towers (flanges, sections), and frames for heavy presses and machinery**. **Available Forms & Processing:** * **Forms:** Hot-rolled plates, sheets, strips, bars (round, flat), and all common structural sections (HE/HL beams, IPE beams, angles, channels). * **Surface:** Standard with mill scale. Commonly available as shot blasted or primed. * **Processing:** Excellent suitability for cutting, welding, drilling, and cold forming. Normalizing or stress relieving can be specified for complex fabrications or to improve properties in thick sections. --- **Important Note:** The guaranteed mechanical properties, especially **yield strength and impact energy, are thickness-dependent**. For material over 40 mm thick, the minimum yield strength is reduced as specified in EN 10025-2. For critical applications (e.g., seismic, offshore, low-temperature), the **quality grade (J2, K2) and any supplementary requirements (e.g., ultrasonic testing, through-thickness properties - EN 10164)** must be clearly specified in the order. Always refer to the mill's inspection certificate (EN 10204 3.1/3.2) for the actual properties of the supplied material. -:- For detailed product information, please contact sales. -: EN 1.0570 High Manganese, Structural, Hot Rolled, Quality Steel Specification Dimensions Size： Diameter 20-1000 mm Length <5800 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 1.0570 High Manganese, Structural, Hot Rolled, Quality Steel Properties -:- For detailed product information, please contact sales. -:
