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."

**Product Name:** EN 1.0595 Structural Steel, Hot Rolled, Quality Grade
**Overview:**
EN 1.0595 is a **high-manganese, non-alloy structural steel** belonging to the S355 strength category, characterized by an enhanced manganese content for improved strength and toughness. It is a quality steel specified under European standards for applications requiring reliable performance under dynamic loads and in moderately low-temperature environments. This grade is primarily intended for welded, bolted, and riveted structures where a balance of good weldability, formability, and cost-effective strength is essential.
**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 & Quality Designation:** EN 1.0595 corresponds to the steel grade **S355**. It is most commonly associated with the **J2** quality class, which guarantees impact toughness at **-20°C**. The exact designation must be specified (e.g., **S355J2**).
* **Equivalents & Comparisons:**
* **ASTM:** A572 Grade 50 (closest mechanical equivalent, Yield 345 MPa).
* **JIS:** SM490A/B/C.
* **GB/T:** Q355D (similar strength and -20°C impact requirements).
* **ISO:** ISO 630-2:2021, Grade E355.
**Chemical Composition (Ladle Analysis, % by weight, max. unless stated otherwise):**
The composition prioritizes strength and toughness through controlled carbon and elevated manganese.
* **Carbon (C):** ≤ **0.20%** (Controlled for weldability).
* **Manganese (Mn):** ≤ **1.60%** (Key feature: High upper limit for strength and hardenability).
* **Phosphorus (P):** ≤ **0.035%**.
* **Sulphur (S):** ≤ **0.035%**.
* **Silicon (Si):** ≤ **0.55%**.
* **Nitrogen (N):** ≤ **0.018%**.
* **Aluminum (Alt):** May be specified for grain refinement in killed steels.
* **Carbon Equivalent (CEV):** Typically in the range of **0.39 - 0.44%**, crucial for welding procedure specification.
**Physical & Mechanical Properties (for hot-rolled condition, thickness ≤ 16 mm):**
* **Yield Strength (ReH):** ≥ **355 MPa** (Minimum for t ≤ 16mm; values decrease with thickness per EN 10025-2 tables).
* **Tensile Strength (Rm):** **470 - 630 MPa**.
* **Elongation at Break (A5):** ≥ **21%** (Minimum, longitudinal test piece).
* **Impact Energy (KV):** **≥ 27 J at -20°C** (Longitudinal, Charpy V-notch, for **S355J2** quality).
* **Density:** **~7.85 g/cm³**.
* **Modulus of Elasticity:** **210 GPa**.
* **Poisson's Ratio:** **0.3**.
**Product Features:**
1. **Good Strength-Toughness Combination:** The high manganese content ensures a robust yield strength (355 MPa) paired with guaranteed impact resistance at -20°C, making it suitable for many outdoor and dynamic applications.
2. **Favorable Weldability:** While requiring more care than S235 steels, it offers good weldability with common arc welding processes. Proper pre-heating (per EN 1011) is recommended for thicker sections and restrained joints to mitigate hydrogen cracking risk.
3. **Economic Efficiency:** Provides a significant strength increase over S275 grades without the cost associated with low-alloy or thermomechanically rolled steels, offering excellent value for many structural applications.
4. **Adequate Formability:** Can be cold formed and machined, though allowances for its higher strength compared to mild steel must be made.
**Typical Applications:**
EN 1.0595 (S355J2) is widely used in general and heavy engineering:
* **General Construction:** Beams, columns, and trusses in industrial buildings, commercial structures, and halls.
* **Bridge Engineering:** Components for road and railway bridges in temperate climates.
* **Crane & Material Handling:** Runway beams for overhead cranes, frames for heavy-duty forklifts, and conveyor supports.
* **Heavy Vehicle Manufacturing:** Chassis components for trucks, trailers, and agricultural machinery.
* **Energy & Infrastructure:** Support structures for power transmission towers and general plant infrastructure.
**Available Forms & Processing:**
* **Forms:** Hot-rolled plates, sheets, strips, bars, and structural sections (beams, channels, angles).
* **Surface:** Typically supplied with mill scale; shot blasting or priming available.
* **Processing:** Well-suited for cutting, welding, drilling, and cold forming. Normalizing can be specified for thicker plates to ensure uniform properties.
---
**Important Note:** Mechanical properties, especially **yield strength and impact energy, are thickness-dependent**. For accurate specification, the required **quality designation (e.g., J2)** and the relevant product thickness must be clearly stated. This grade is a reliable, all-purpose structural steel for applications where S275 strength is insufficient and where service temperatures may occasionally reach -20°C. For more severe conditions (e.g., offshore, arctic), grades with higher toughness (like S355K2 or NL/ML grades per EN 10225) should be considered.
