### **Product Data Sheet: Alloy B / Brightray B High-Temperature Alloy Sheet** **1. Product Overview** **Brightray B** (Alloy B) is a premier nickel-chromium (80/20) resistance heating alloy, offering an exceptional combination of high-temperature strength, oxidation resistance, and fabricability. This datasheet provides detailed information on the **sheet** form of this alloy, which is characterized by its relatively thin cross-section and large surface area. Brightray B sheet is the ideal material for constructing furnace linings, heat shields, and other critical components where a combination of formability and extreme temperature performance is required. When heated, the alloy forms a dense, adherent layer of chromium oxide on the surface, which acts as a protective barrier, ensuring long-term stability and resistance to degradation in oxidizing atmospheres. **2. Chemical Composition (Typical % by Weight)** The chemical composition is precisely controlled to ensure consistent performance in high-temperature sheet applications. | Element | Content (%) | Function | | :--- | :--- | :--- | | Nickel (Ni) | 80 | Base element, provides austenitic structure, ductility, and corrosion resistance. | | Chromium (Cr) | 20 | Key for forming the protective Cr₂O₃ oxide scale for oxidation resistance. | | Iron (Fe) | ≤ 1.0 | Residual impurity. | | Carbon (C) | ≤ 0.15 | Controlled to optimize strength while maintaining fabricability. | | Manganese (Mn) | ≤ 1.0 | Acts as a deoxidizer during melting. | | Silicon (Si) | ≤ 1.0 | Enhances scale adherence and further improves oxidation resistance. | | Copper (Cu) | ≤ 0.5 | Residual impurity. | | Sulfur (S) | ≤ 0.015 | Residual impurity; kept minimal to prevent hot shortness. | **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 sheet is engineered for applications requiring a formable yet durable material capable of withstanding sustained high temperatures. * **Furnace Construction:** Internal linings, heat shields, inner covers, and radiant boxes. * **Heat Treatment Fixturing:** Baskets, trays, and wrappers for annealing, sintering, and brazing processes. * **Combustion Systems:** Heat shields, burner parts, and liners for industrial burners and combustors. * **Aerospace & Power Generation:** Components for jet engines, exhaust systems, and thermal management units. * **Appliance Manufacturing:** Internal heat-reflecting liners and components in high-temperature domestic and commercial appliances. * **Chemical Processing:** Reactor vessel linings and components exposed to corrosive high-temperature atmospheres. **5. Key Features & Benefits** * **Excellent Oxidation Resistance:** Designed for continuous service in air at temperatures up to **1150°C**. * **Superior Fabricability:** The sheet form is supplied in an annealed state, allowing for excellent bending, stamping, deep drawing, and roll-forming capabilities. * **High Strength at Temperature:** Maintains mechanical strength and resists sagging or distortion under its own weight at operating temperatures. * **Long Service Life:** The stable and self-healing oxide layer ensures extended component life, reducing downtime and operational costs. * **Good Weldability:** Can be readily welded using matching filler metals (e.g., AWS ERNiCr-3) or other compatible nickel-alloy electrodes using TIG, MIG, and plasma arc welding processes. **6. International Standards** Brightray B sheet conforms to several key international standards for sheet and strip products. * **ASTM:** **ASTM B168** - Standard Specification for Seamless Nickel-Chromium-Iron Alloy Plate, Sheet, and Strip. * **UNS Number:** **N06003** * **DIN:** **DIN 17750** (Material No. 2.4869 - NiCr80/20). * **EN:** **EN 10095** (NiCr80/20 is a common industry equivalent for heat-resisting steels and alloys). * **BS:** **BS 972** (Alloy 2 - Ni80/Cr20). * **JIS:** **JIS G 4902** (Heat-resisting nickel-chromium steel plate and sheet - NCF 2). **7. Product Form & Availability** * **Form:** Sheet, Strip, Foil. * **Thickness Range:** Typically available from 0.5mm up to 3.0mm (or as defined by the supplier's distinction between sheet and plate). * **Condition:** Supplied in a solution-annealed and pickled condition, ensuring a scale-free surface ideal for fabrication and service. * **Surface Finish:** Standard mill finish (pickled). Other finishes, such as cold-rolled or polished, may be available. --- **Disclaimer:** The information provided herein is typical and for reference purposes.
