### **Product Data Sheet: Alloy B / Brightray B High-Temperature Alloy Plate** **1. Product Overview** Alloy B, widely known by the trade name **Brightray B**, is a nickel-chromium (80/20) alloy renowned for its exceptional resistance to oxidation at high temperatures. This datasheet specifically details the **plate** form of this versatile alloy. Brightray B plate offers the same superior high-temperature properties as the wire and tube forms, but in a format designed for structural components, furnace fixtures, and heat-processing equipment requiring robust, sheet-like configurations. The alloy's high nickel content provides excellent resistance to thermal cycling and corrosion, while the chromium content forms a continuous, protective chromium oxide scale when heated, ensuring long service life in oxidizing atmospheres. **2. Chemical Composition (Typical % by Weight)** The composition is meticulously controlled to deliver optimal high-temperature performance and fabricability in plate form. | Element | Content (%) | Function | | :--- | :--- | :--- | | Nickel (Ni) | 80 | Base element, provides metallurgical stability and corrosion resistance. | | Chromium (Cr) | 20 | Imparts oxidation resistance by forming a protective Cr₂O₃ scale. | | Iron (Fe) | ≤ 1.0 | Residual impurity. | | Carbon (C) | ≤ 0.15 | Controlled to maintain formability and minimize embrittlement. | | Manganese (Mn) | ≤ 1.0 | Aids in deoxidation during the melting process. | | Silicon (Si) | ≤ 1.0 | Enhances scale adherence and high-temperature strength. | | Copper (Cu) | ≤ 0.5 | Residual impurity. | | Sulfur (S) | ≤ 0.015 | Residual impurity; kept very low to preserve hot workability. | **3. Physical & Mechanical Properties (Typical for Annealed Condition)** | Property | Value / Description | | :--- | :--- | | **Density** | 8.41 g/cm³ (0.304 lb/in³) | | **Melting Point** | Approx. 1400°C (2550°F) | | **Specific Heat Capacity** | 440 J/kg·K at 20°C | | **Thermal Conductivity** | 12.5 W/m·K at 20°C | | **Coefficient of Thermal Expansion** | 17.0 μm/m·K (20-1000°C) | | **Modulus of Elasticity** | 214 GPa at 20°C | | **Tensile Strength** | 620 - 760 MPa | | **Yield Strength (0.2% Offset)** | 250 MPa (min) | | **Elongation** | 30% (min) | | **Hardness (Rockwell B)** | 65 - 85 HRB | **4. Product Applications** Brightray B plate is specified for demanding applications where flat or formed components are exposed to high temperatures and oxidizing environments. * **Furnace Components:** Radiant tubes, muffles, retorts, inner covers, and furnace linings. * **Heat Treatment Fixtures:** Baskets, trays, jigs, and fixtures for annealing, carburizing, and brazing processes. * **Heat Exchangers & Combustors:** Components in industrial heating systems requiring structural integrity at high temperatures. * **Aerospace & Turbo Machinery:** Heat shields, combustor liners, and afterburner components. * **Chemical Processing:** Structural parts in high-temperature processing vessels and reactors. * **Glass Manufacturing:** Support structures and components within glass processing furnaces. **5. Key Features & Benefits** * **Superior Oxidation Resistance:** Excellent for continuous service in air at temperatures up to **1150°C**. * **High Strength at Elevated Temperatures:** Maintains structural integrity and resists creep and sagging under load at high temperatures. * **Excellent Fabricability:** Plates can be sheared, punched, plasma-cut, and formed into complex shapes in the annealed condition. It is also readily weldable using matching or compatible filler metals. * **Long Service Life:** The stable, adherent oxide scale minimizes material degradation, leading to reduced maintenance and replacement frequency. * **Thermal Stability:** Resists embrittlement and microstructural changes during prolonged exposure to high temperatures. **6.
