### **Product Introduction: Alloy 450 & Monel 450 Fittings** #### **Overview** We specialize in manufacturing high-performance piping fittings from two superior nickel-based alloys: **Alloy 450 (UNS N06450)** and **Monel 450 (UNS N05500)**. Our fittings, including elbows, tees, reducers, caps, and flanges, are precision-engineered to ensure leak-proof integrity, dimensional accuracy, and exceptional resistance to corrosion and high temperatures. Selecting the correct alloy is paramount for the safety and longevity of your piping systems. --- ### **Part 1: Alloy 450 (UNS N06450) Fittings** Alloy 450 is a **nickel-chromium-iron alloy** designed for extreme temperature service. It offers outstanding resistance to oxidation and possesses high strength, making it the ideal choice for furnace and heat treatment applications. #### **Key Features & Advantages** * **Exceptional Oxidation Resistance:** Suitable for continuous service up to 1177°C (2150°F). * **High-Temperature Strength:** Retains structural integrity under heavy loads at elevated temperatures. * **Thermal Stability:** Resists embrittlement from sigma phase formation during long-term exposure. * **Good Weldability:** Fittings can be easily welded to piping systems using matching filler metals. #### **Chemical Composition (Typical % Weight)** | Element | Content (%) | | :--- | :--- | | **Nickel (Ni)** | 73.0 min | | **Chromium (Cr)** | 14.0 - 18.0 | | **Iron (Fe)** | 5.0 - 9.0 | | **Manganese (Mn)** | 1.0 max | | **Silicon (Si)** | 0.5 max | | **Copper (Cu)** | 0.5 max | | **Carbon (C)** | 0.15 max | | **Sulfur (S)** | 0.015 max | #### **Physical & Mechanical Properties (Annealed Condition)** | Property | Value | | :--- | :--- | | **Density** | 8.22 g/cm³ (0.297 lb/in³) | | **Melting Point** | ~1371°C (~2500°F) | | **Tensile Strength** | 655 MPa (95 ksi) min | | **Yield Strength (0.2% Offset)** | 275 MPa (40 ksi) min | | **Elongation** | 30 % min | #### **International Standards (Alloy 450 Fittings)** * **ASTM / ASME:** * **Pipe Fittings (Elbows, Tees):** ASTM B / SB 366 * **Flanges:** ASTM B / SB 462 * **Forged Fittings:** ASTM B / SB 564 (forging stock) * **UNS:** **N06450** * **EN:** **NW 8345** (NiCr15Fe) #### **Applications (Alloy 450 Fittings)** * **Heat Treatment Furnaces:** Radiant tube assemblies, retort connections, thermocouple wells. * **Power Generation:** Exhaust system ducting, expansion joints in high-temperature gas paths. * **Chemical Processing:** High-temperature transfer lines in calciners and roasters. * **Aerospace:** Engine test bed piping and components. --- ### **Part 2: Monel 450 (UNS N05500) Fittings** Monel 450, universally known as **Monel K-500**, is a **precipitation-hardenable nickel-copper alloy**. It provides the excellent corrosion resistance of Monel 400 with the added advantage of significantly higher strength and hardness achieved through heat treatment (aging). This makes it perfect for high-strength, corrosion-resistant piping systems. #### **Key Features & Advantages** * **High Strength & Hardness:** Can be supplied in the aged condition to withstand high pressure and mechanical wear. * **Superb Corrosion Resistance:** Excellent resistance to seawater, sulfuric and hydrofluoric acids, and alkaline solutions. * **Low Magnetic Permeability:** Ideal for non-magnetic applications in marine and scientific instrumentation. * **Excellent Erosion-Corrosion Resistance:** Perfect for high-velocity seawater and slurry-handling systems. #### **Chemical Composition (Typical % Weight)** | Element | Content (%) | | :--- | :--- | | **Nickel (Ni)** | 63.0 min | | **Copper (Cu)** | 27.0 - 33.0 | | **Aluminum (Al)** | 2.30 - 3.15 | | **Titanium (Ti)** | 0.35 - 0.85 | | **Iron (Fe)** | 2.0 max | | **Manganese (Mn)** | 1.5 max | | **Carbon (C)** | 0.25 max | | **Silicon (Si)** | 0.5 max | #### **Physical & Mechanical Properties** *Properties for fittings are typically provided in the aged condition for maximum performance.* | Property | Aged Condition (Typical for Fittings) | | :--- | :--- | | **Density** | 8.44 g/cm³ (0.305 lb/in³) | | **Melting Point** | ~1316°C (~2400°F) | | **Tensile Strength** | 965-1207 MPa (140-175 ksi) | | **Yield Strength (0.2% Offset)** | 655-1035 MPa (95-150 ksi) | | **Elongation** | 15-25 % | | **Hardness (Rockwell)** | C25 - C38 | #### **International Standards (Monel 450 Fittings)** * **ASTM / ASME:** * **Pipe Fittings (Elbows, Tees):** ASTM B / SB 366 * **Flanges:** ASTM B / SB 462 * **Forged Fittings:** ASTM B / SB 564 (This is the primary standard for Ni-Cu alloy forgings) * **UNS:** **N05500** * **Common Trade Name:** **Monel® K-500**. #### **Applications (Monel 450 Fittings)** * **Marine & Offshore:** Seawater piping systems, pump discharge fittings, ballast line components, deck drain systems. * **Oil & Gas:** High-pressure wellhead components, choke and kill line fittings, chemical injection skid piping. * **Chemical Processing:** Heat exchanger nozzles, reactor feed fittings, and piping handling hydrofluoric acid. * **Desalination Plants:** High-pressure brine heater fittings and inter-connecting piping. --- ### **Selection Guide & Our Capabilities** | Feature | Alloy 450 (UNS N06450) | Monel 450 (UNS N05500) | | :--- | :--- | :--- | | **Alloy System** | Nickel-Chromium-Iron | Nickel-Copper (Age-Hardenable) | | **Primary Advantage** | High-Temperature Oxidation Resistance | High Strength + Seawater Corrosion Resistance | | **Typical Fitting Use** | Furnace Piping, Exhaust Systems | Marine, Oil & Gas, Chemical Process Piping | **Our Fittings Capabilities:** We supply a comprehensive range of fittings in both alloys, manufactured to the highest standards. * **Types:** Elbows (90°/45°), Tees (Equal/Reducing), Reducers (Concentric/Eccentric), Caps, Stub Ends, Nipples. * **Specifications:** Manufactured to ASTM/ASME standards, with full traceability and MTC (Mill Test Certificate). * **Condition:** Supplied in solution annealed or precipitation hardened (aged) condition as required. **Why Choose Us?** * Deep expertise in machining and forging nickel alloys. * Strict quality control ensuring pressure integrity and dimensional accuracy. * Technical support to help you select the optimal material and specification. **Contact us today for your Alloy 450 and Monel 450 (K-500) fitting requirements.** --- ***Disclaimer:*** *Monel® is a registered trademark of Special Metals Corporation.
