### **Product Introduction: Alloy 801 / Incoloy 801 / UNS N08801 Strip** **Overview** Alloy 801 (Incoloy 801) is a nickel-iron-chromium alloy stabilized with titanium, specifically designed for high-temperature service. In its **strip** form, this alloy is cold-rolled to precise thicknesses, offering a superior surface finish, tight dimensional tolerances, and excellent flatness. This makes Incoloy 801 strip an ideal material for high-performance applications requiring intricate forming, stamping, or blanking, such as thermocouple sheaths, industrial furnace components, and precision gaskets. Its primary attributes include outstanding resistance to oxidation and carburization, making it a cost-effective solution for long-term use in temperatures up to 1100°C (2012°F). **Key Characteristics of Strip Form** * **Excellent Formability:** The strip can be readily deep drawn, stamped, and formed into complex shapes. * **Precision Gauge and Width:** Available in thin, uniform gauges with precise widths for automated production. * **Superior Surface Finish:** Typically supplied with a descaled, bright, or pickled finish suitable for final applications. * **High-Temperature Strength:** Maintains mechanical integrity and resists creep under thermal and mechanical stress. * **Oxidation & Carburization Resistance:** Excellent resistance to scaling in air and to carbon absorption in carburizing atmospheres. * **Good Weldability:** Can be welded using common techniques like TIG and resistance welding. --- ### **Chemical Composition (Weight %)** The typical chemical composition of UNS N08801 strip conforms to the following standard requirements: | Element | Content (%) | | :--- | :--- | | **Nickel (Ni)** | 30.0 - 34.0 | | **Chromium (Cr)** | 19.0 - 22.0 | | **Iron (Fe)** | Balance | | **Carbon (C)** | 0.05 - 0.10 | | **Titanium (Ti)** | 0.15 - 0.60 | | **Aluminum (Al)** | ≤ 0.30 | | **Manganese (Mn)** | ≤ 1.50 | | **Silicon (Si)** | ≤ 1.00 | | **Copper (Cu)** | ≤ 0.75 | | **Sulfur (S)** | ≤ 0.015 | *The balance is Iron (Fe). Composition is controlled for optimal high-temperature performance and formability.* --- ### **Physical Properties** Typical physical properties for Incoloy 801 strip are consistent with other product forms. | Property | Value | | :--- | :--- | | **Density** | 7.95 g/cm³ (0.287 lb/in³) | | **Melting Range** | 1350 - 1400 °C (2460 - 2550 °F) | | **Specific Heat (20°C)** | 450 J/kg·K | | **Electrical Resistivity** | 1.00 μΩ·m | | **Thermal Conductivity (20°C)** | 11.9 W/m·K | | **Mean Coefficient of Thermal Expansion (20-1000°C)** | 14.7 x 10⁻⁶ /°C | --- ### **Mechanical Properties (Typical for Annealed Strip)** The mechanical properties of strip can be tailored through cold working and annealing to meet specific application needs (e.g., spring temper). The following are typical for annealed strip. | Property | Value | | :--- | :--- | | **Tensile Strength** | 520 - 690 MPa (75 - 100 ksi) | | **Yield Strength (0.2% Offset)** | 205 - 345 MPa (30 - 50 ksi) | | **Elongation** | ≥ 30% | | **Hardness (Rockwell B)** | 75 - 85 HRB | --- ### **Product Applications** The strip form of Incoloy 801 is essential for manufacturing precision components, including: * **Thermocouple Sheaths:** Thin-walled, closed-end tubes formed from strip to protect thermocouple wires in high-temperature furnaces. * **Industrial Furnace Components:** Blanketed and formed into radiant tubes, inner liners, muffles, and heat treatment baskets. * **Gaskets and Seals:** Stamped into high-temperature seals and gaskets for flanges and furnace doors. * **Electrical and Heating Elements:** Used as support hooks, spacers, and lead wires. * **Chemical Processing:** Components for reactors and heat exchangers requiring formed parts from thin, corrosion-resistant material. * **Automotive & Aerospace:** Exhaust and turbine components requiring precision-formed parts. --- ### **International Standards** Incoloy 801 strip is covered by several key international standards that define its chemical, mechanical, and dimensional requirements. | Standard Type | Standard Number | Title / Specification | | :--- | :--- | :--- | | **Material Standard (ASTM)** | **ASTM B409** | Standard Specification for Nickel-Iron-Chromium Alloy Plate, Sheet, and Strip | | **Material Standard (ASME)** | **ASME SB-409** | Identical to ASTM B409 for ASME Code construction (e.g., pressure vessels) | | **Aerospace Material (AMS)** | **AMS 5512** | Sheet, Strip, and Plate; Nickel Alloy, Corrosion and Heat-Resistant, 32Ni-21Cr- 46Fe (UNS N08801) Annealed | | **UNS Designation** | **N08801** | Unified Numbering System | | **Werkstoff Number** | **1.4875** | German material identification number | | **European Standard** | **EN 10095** | Heat resisting steels and nickel alloys | *Note: Strip is typically supplied to ASTM B409, with AMS 5512 being a common specification for aerospace and other high-reliability industries.
