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 Datasheet: ATI Allvac® VascoJet® 1000 Ultra-High-Strength Steel (Q+T Condition)**
**ATI Allvac® VascoJet® 1000** is a cobalt-nickel secondary hardening ultra-high-strength steel, representing the pinnacle of commercially available strength-to-toughness combinations. It was developed specifically for aerospace applications requiring **extreme strength, excellent fracture toughness, and good stress corrosion cracking resistance**. The **1010°C (1850°F) Quench and Temper (Q+T)** heat treatment process unlocks its unparalleled mechanical properties.
#### **1. Key Characteristics & Advantages**
* **Unmatched Strength-Toughness Combination:** Achieves tensile strengths exceeding **1,930 MPa (280 ksi)** while maintaining exceptional fracture toughness, a rare and critical combination.
* **Secondary Hardening:** Gains strength and hardness during tempering due to the precipitation of fine intermetallic phases, allowing for high-temperature stability.
* **Excellent Stress Corrosion Cracking (SCC) Resistance:** Superior to many other ultra-high-strength steels like 4340 or 300M, making it suitable for demanding environments.
* **Deep Hardenability:** Can be through-hardened in substantial sections with minimal distortion due to its high alloy content and air-hardening capability.
* **Good Weldability (with precautions):** Can be welded using proper techniques, which is exceptional for a steel at this strength level.
#### **2. Standard Specifications & International Designations**
* **Proprietary Grade:** VascoJet 1000 is a trademarked grade. It is not covered by common AISI/SAE standards.
* **AMS:** Often supplied to meet the requirements of **AMS 6528** (Steel, Corrosion-Resistant, Investment Castings) or customer-specific aerospace material specifications.
* **U.S. Military:** Conforms to **MIL-S-89485**.
* **EURONORM / ISO:** No direct equivalent. It is typically specified under proprietary or project-specific designations in international programs.
#### **3. Chemical Composition (Typical, Weight %)**
| Element | Content (%) | Element | Content (%) |
| :--- | :--- | :--- | :--- |
| **Carbon (C)** | 0.23 - 0.27 | **Cobalt (Co)** | 12.00 - 13.00 |
| **Nickel (Ni)** | 10.00 - 11.00 | **Chromium (Cr)** | 2.50 - 3.25 |
| **Molybdenum (Mo)** | 1.20 - 1.50 | **Vanadium (V)** | 0.07 - 0.12 |
| **Silicon (Si)** | 0.10 max | **Manganese (Mn)** | 0.10 max |
| **Sulfur (S)** | ≤ 0.005 | **Phosphorus (P)** | ≤ 0.010 |
| **Iron (Fe)** | Balance |
#### **4. Heat Treatment: 1010°C (1850°F) Quench & Temper**
This specific thermal cycle is critical for developing the optimal microstructure:
* **Austenitizing:** Heat to **1010°C (1850°F)** and hold to achieve full solutioning of alloying elements.
* **Quenching:** Cool in **air or positive pressure gas**. The high alloy content ensures full martensite transformation with low risk of distortion or cracking.
* **Cryogenic Treatment:** A sub-zero treatment (e.g., -73°C / -100°F) is typically performed immediately after quenching to transform retained austenite and maximize stability.
* **Tempering (Double or Triple Temper):** Performed at **480°C to 510°C (900°F to 950°F)**. This is where **secondary hardening** occurs, precipitating complex (Co, Mo, Ni) intermetallics, leading to peak strength and toughness.
* **Final Hardness:** Typically **HRC 54 - 58**, resulting in its ultra-high strength.
#### **5. Typical Physical & Mechanical Properties (After Q+T)**
* **Density:** 7.99 g/cm³ (0.289 lb/in³)
* **Modulus of Elasticity:** 200 GPa (29 x 10⁶ psi)
* **Ultimate Tensile Strength:** **1,930 - 2,070 MPa (280 - 300 ksi)**
* **Yield Strength (0.2% Offset):** **1,790 - 1,930 MPa (260 - 280 ksi)**
* **Elongation:** 10 - 14%
* **Reduction in Area:** 45 - 55%
* **Fracture Toughness (KIc):** **110 - 130 MPa√m (100 - 120 ksi√in)** – Exceptional at this strength level.
* **Hardness:** **54 - 58 HRC**

#### **7. Availability & Processing Notes**
* **Forms Available:** Primarily available as premium **Vacuum Induction Melted + Vacuum Arc Remelted (VIM-VAR)** forgings, billets, and bars to ensure ultra-cleanliness and homogeneity.
* **Machining:** Must be machined in the annealed or normalized condition. Finish machining after heat treatment is difficult and typically limited to grinding or EDM.
