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 Data Sheet: AISI 1110 Steel Composition Specification (UNS G11100)**
#### **1. Overview**
AISI 1110 (UNS G11100) is a low-carbon, non-resulfurized manganese steel. As a composition specification, it defines a material with slightly higher carbon and manganese content than the most basic low-carbon steels (e.g., 1008, 1010). This combination provides a balanced profile of **good formability, fair machinability, and a moderate response to work hardening and case hardening**. It is commonly used as a general-purpose, low-cost steel for parts that require a combination of light forming and machining, and can serve as a core material for carburized components where a tougher, stronger base than 1010 is desired.
---
#### **2. Chemical Composition (AISI/SAE Standard)**
| Element | Content (%) |
| :--- | :--- |
| **Carbon (C)** | 0.08 - 0.13 |
| **Manganese (Mn)** | **0.30 - 0.60** |
| **Phosphorus (P)** | ≤ 0.040 |
| **Sulfur (S)** | ≤ 0.050 |
| **Iron (Fe)** | Balance |
**Key Distinction:** Compared to AISI 1010 (Mn: 0.30-0.60%), the carbon range is identical. The primary difference from the **1108** grade is the **absence of added sulfur** for free-machining properties. Compared to **1015**, it has a slightly lower carbon upper limit.
---
#### **3. Typical Physical & Mechanical Properties**
*Properties vary significantly based on processing condition (hot-rolled, cold-drawn, annealed). Below are representative ranges.*
| Property / Condition | Hot-Rolled (As-Rolled) | Cold-Drawn / Work-Hardened | Annealed (Soft) |
| :--- | :--- | :--- | :--- |
| **Tensile Strength** | 365 - 460 MPa (53 - 67 ksi) | 420 - 550 MPa (61 - 80 ksi) | 320 - 400 MPa (46 - 58 ksi) |
| **Yield Strength** | 200 - 295 MPa (29 - 43 ksi) | 350 - 480 MPa (51 - 70 ksi) | 180 - 250 MPa (26 - 36 ksi) |
| **Elongation (in 50mm)** | ~ 25 - 35% | ~ 15 - 22% | ~ 30 - 40% |
| **Hardness (Approx.)** | ~ 100-130 HB | ~ 120-160 HB | ~ 90-110 HB |
| **Machinability** | Fair (~70% of AISI 1212) | Fair to Good | Fair (softer but gummier) |
| **Primary Characteristic** | Low cost, good formability. | Increased strength, better finish/tolerance. | Maximum ductility for severe forming. |
**General Characteristics:**
* **Density:** 7.87 g/cm³
* **Modulus of Elasticity:** 190-205 GPa (28,000-29,700 ksi)
* **Hardenability:** Very low. Not suitable for through-hardening (quenching & tempering). **Excellent candidate for case hardening** (e.g., carburizing, carbonitriding) due to low core carbon content.
* **Weldability:** **Excellent.** Low carbon equivalent makes it highly weldable by all common processes with minimal pre-heat.
---
#### **4. Key Characteristics & Metallurgical Behavior**
* **Good Formability and Weldability:** The low carbon content ensures high ductility and excellent weldability, making it suitable for fabricated structures and formed parts.
* **Non-Free-Machining:** Unlike the 11xx series with sulfur (e.g., 1108, 1117), AISI 1110 does not contain added sulfur for chip breaking. Machinability is standard for a low-carbon steel and is less than that of free-machining grades.
* **Response to Cold Work:** Readily work hardens during cold forming or drawing, which can be used to increase its strength.
* **Ideal for Case Hardening:** Its low core carbon provides a tough and ductile substrate, while the surface can be enriched with carbon (carburized) and hardened to create a wear-resistant component with a resilient core.
---
#### **5. Typical Product Applications**
AISI 1110 is used for a wide variety of low-stress, general engineering components.
* **Cold Formed & Headed Parts:** Nuts, bolts, rivets, clips, and other fasteners or small stampings.
* **Structural & Fabricated Components:** Light brackets, frames, and supports where weldability is important.
* **Shafts & Pins for Light Duty:** Non-critical axles, rollers, and hinge pins.
* **Case Hardened Components:** Gears, pins, camshafts, and other parts that are carburized or carbonitrided to achieve a hard, wear-resistant surface over a tough core. (Often specified as **1110 Carburizing Grade**).
* **General Machined Parts:** Where machinability is not the sole critical factor and parts will be case hardened or used as-is for low-strength applications.

### **Processing & Selection Notes**
1. **Condition Selection:** Choose the product form (hot-rolled, cold-drawn, annealed) based on the initial fabrication method (forming vs. machining) and required strength.
2. **Case Hardening Pathway:** For wear applications: Machine/Form -> Carburize -> Quench & Temper (low temperature) -> Finish Grind.
3. **Machining Consideration:** For parts requiring extensive machining, a free-machining grade like **1117** (resulfurized) or **12L14** (leaded) would be more economical.
4. **Direct Replacement:** Often interchangeable with **AISI 1010, 1015**, with minor variations in properties. **1018** offers higher manganese for slightly better hardenability if needed.
**Summary:** **AISI 1110 (UNS G11100) is a versatile, low-carbon, non-alloy steel specification.** It serves as a **general-purpose workhorse material** valued for its good formability, excellent weldability, and suitability for case hardening. Its applications bridge simple formed parts and more durable case-hardened components. While not specialized for maximum machinability or strength, it offers a reliable and cost-effective balance of properties for a wide range of low-to-moderate duty engineering applications.
