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.

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 S235JRG1C High Manganese, Structural, Hot Rolled, Quality Steel Flange Product Information -:- For detailed product information, please contact sales. -: EN S235JRG1C High Manganese, Structural, Hot Rolled, Quality Steel Flange Synonyms -:- For detailed product information, please contact sales. -:

EN S235JRG1C High Manganese, Structural, Hot Rolled, Quality Steel Product Information -:- For detailed product information, please contact sales. -: **Product Name:** EN S235JRG1C Structural Steel for Cold Forming, Hot Rolled, As-Rolled Condition **Overview:** EN S235JRG1C is a **specialized non-alloy structural steel** defined under the EN 10025-2 standard. It belongs to the S235 strength category and combines two specific supplementary designations: **"G1"** for its delivery condition and **"C"** for its intended use. This designation explicitly describes a steel that is supplied in the standard **as-hot-rolled condition (G1)** and is **chemically optimized for cold forming (C)**. It is engineered to provide superior ductility and resistance to cracking during manufacturing processes such as bending, stamping, or roll-forming. It is **not a "High Manganese" steel**; its defining characteristic is its enhanced cold workability. **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 Decoding:** **S235JRG1C** * **S:** Structural Steel. * **235:** Minimum yield strength in MPa (for thickness ≤ 16mm). * **JR:** Base quality designation. Impact tested at **+20°C (Room Temperature)**. * **G1:** Supplementary designation for the **delivery condition**, meaning **hot-rolled, as-rolled (AR)**. It is the standard delivery state. * **C:** **Critical supplementary designation** for **steels intended for cold forming**. * **Core Concept:** This is a **cold-forming grade in its most common, as-rolled state**. The "G1C" combination ensures the material has the chemical composition for formability while being supplied in the standard mill condition without additional heat treatment. * **Clarification on "High Manganese":** This is **incorrect and misleading**. The manganese content is standard for S235. The premium is paid for the **controlled chemistry for forming ("C")**, not for alloy content. * **Equivalents:** No direct equivalent in other standards due to the specific EN "C" classification. Loosely comparable to cold-forming grades of ASTM A36 or A283. **Chemical Composition (Ladle Analysis, % by weight, maximum values per EN 10025-2 for 'C' grades):** Tighter controls on residual elements to facilitate cold forming. * **Carbon (C):** ≤ **0.17%** (Often targeted lower). * **Manganese (Mn):** ≤ **1.40%** (Standard, not elevated). * **Phosphorus (P):** ≤ **0.030%** (**Key Differentiator** - Tighter than the 0.045% limit for standard S235JR/G1). * **Sulphur (S):** ≤ **0.030%** (**Key Differentiator** - Tighter than the 0.045% limit for standard S235JR/G1). * **Nitrogen (N):** ≤ **0.014%**. **Physical & Mechanical Properties (for hot-rolled/as-rolled 'G1' condition, thickness ≤ 16mm):** * **Yield Strength (ReH):** ≥ **235 MPa** (Minimum for t ≤ 16mm). * **Tensile Strength (Rm):** **360 - 510 MPa**. * **Elongation at Break (A5):** ≥ **26%** (Minimum, typically good due to favorable chemistry). * **Impact Energy (KV):** ≥ **27 J at +20°C**. **No toughness guarantee exists below +20°C.** * **Cold Formability:** **Excellent.** The primary feature. The steel is certified to undergo significant cold deformation in its as-rolled state with a **markedly reduced risk of edge or bend cracking** compared to standard S235JRG1. * **Delivery Condition:** **As-Hot-Rolled (G1)**. The properties are a direct result of the rolling process. * **Density:** **~7.85 g/cm³**. **Product Features:** 1. **Optimized for Cold Forming in Standard State:** Provides the best balance of cost and performance for fabrication shops that require good cold formability without the expense of normalized or TM-rolled steel. 2. **Maintained Base Properties:** Retains the strength, weldability, and general fabricability of the base S235 grade. 3. **Cost-Effective for Fabrication:** While slightly more expensive than S235JRG1, it prevents costly scrap from cracking during forming operations, improving overall production yield. 4. **Predictable As-Rolled Behavior:** Offers consistent performance for standard cold-forming applications. **Typical Applications:** S235JRG1C is specified for components that are cold-formed from standard hot-rolled stock. * **General Fabrication:** **Press-braked brackets, chassis parts, frames, and supports** made from plate or flat bar. * **Construction:** **Cold-bent connection plates, base plates, and stiffeners**. * **Storage & Handling:** **Components for shelving and racking systems** formed from hot-rolled sheet. * **Transportation:** **Non-critical formed parts for trailers and bodies**. **Available Forms & Processing:** * **Forms:** Hot-rolled plates, sheets, strips, and flat bars. * **Surface:** Typically with mill scale. Can be shot blasted or pickled. * **Processing:** **Ideal for press-brake bending, roll-forming, and stamping.** Excellent for welding and cutting. --- **Critical Procurement Note:** * **Must Specify "C":** Ordering **S235JRG1** (without C) will result in standard material not suited for aggressive cold forming. The "C" is essential. * **Temperature Limitation:** This is a **JR grade**. It is **unsuitable** for service temperatures below **0°C** under dynamic loading. For cold-formed parts in cold environments, a grade with both "C" and low-temperature toughness (e.g., **S235J2C**) is required. * **Not "High Manganese":** Do not use this term. Correctly describe it as **"Cold-Formable As-Rolled Structural Steel."** * **Thickness Consideration:** Mechanical properties are thickness-dependent. Confirm the applicable yield strength for the ordered thickness. -:- For detailed product information, please contact sales. -: EN S235JRG1C High Manganese, Structural, Hot Rolled, Quality Steel Specification Dimensions Size： Diameter 20-1000 mm Length <5816 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 S235JRG1C High Manganese, Structural, Hot Rolled, Quality Steel Properties -:- For detailed product information, please contact sales. -:
