**Technical Datasheet: Alloy S (UNS N06635) Foil & Shim** --- ### **Overview** Alloy S Foil and Shim, commercially known as **Hastelloy® S**, are ultra-thin gauge forms of the nickel-chromium-molybdenum superalloy UNS N06635. These products are engineered for applications requiring minimal thickness, exceptional high-temperature stability, and superior oxidation resistance. The foil (typically <0.1 mm) and shim (0.1–1.0 mm) forms provide flexible, precision solutions for thermal management, sealing, and spacing in extreme environments up to 1200°C (2200°F). --- ### **Chemical Composition (Weight %)** | Element | Content (%) | |---------|-------------| | Nickel (Ni) | Balance | | Chromium (Cr) | 14.0–16.0 | | Molybdenum (Mo) | 14.0–16.0 | | Iron (Fe) | ≤3.0 | | Tungsten (W) | ≤1.0 | | Cobalt (Co) | ≤2.0 | | Manganese (Mn) | ≤0.50 | | Silicon (Si) | ≤0.40 | | **Lanthanum (La)** | **≥0.02** | | Carbon (C) | ≤0.015 | | Boron (B) | ≤0.010 | --- ### **Physical & Mechanical Properties** | Property | Value | |----------|-------| | **Density** | 8.86 g/cm³ | | **Melting Range** | 1335–1380°C | | **Thermal Conductivity** | 11.0 W/m·K (20°C) | | **Coefficient of Thermal Expansion** | 12.8 μm/m·°C (20–100°C) | | **Tensile Strength** | 795–895 MPa | | **Yield Strength (0.2% Offset)** | 345–415 MPa | | **Elongation** | 35–45% | --- ### **Product Applications** 1. **Thermal Management**: Heat shields, radiation baffles, and thermal blankets in furnaces and aerospace systems. 2. **Sealing & Gasketing**: High-temperature gaskets, seals, and packing for aggressive chemical and thermal environments. 3. **Shimming & Spacing**: Precision shims for aligning components in turbines, pumps, and high-temperature machinery. 4. **Electronics & Sensors**: Substrates or protective layers for high-temperature sensors and electronic devices. 5. **Laboratory & Research**: Liners, spacers, and containment foils for experimental setups involving molten salts or corrosive gases. --- ### **Standard Specifications** | Product Form | Thickness Range | Width Range | Common Standards | |--------------|----------------|-------------|------------------| | **Foil** | 0.025–0.1 mm | 50–600 mm | ASTM B575, AMS 5790 | | **Shim** | 0.1–1.0 mm | 50–600 mm | ASTM B575, AMS 5790, ASME SB-575 | --- ### **International Standards** - **ASTM B575**: Low-Carbon Nickel-Molybdenum-Chromium Alloy Plate, Sheet, and Strip. - **ASME SB-575**: Code-approved version for pressure equipment. - **AMS 5790**: Aerospace Material Specification for sheet, strip, and foil. - **ISO 6208**: Nickel and nickel alloy thin sheets/strips. - **UNS N06635**: Unified Numbering System designation. --- ### **Key Features** - **Oxidation Resistance**: Lanthanum stabilization prevents scale spallation under thermal cycling. - **Flexibility & Formability**: Can be stamped, bent, or wrapped without cracking. - **Corrosion Resistance**: Suitable for oxidizing, sulfidizing, and carburizing atmospheres. - **Consistent Thickness**: Tight tolerances for precision applications. --- ### **Notes** - Available in rolls, sheets, or custom-cut shapes. - Surface finishes include annealed, pickled, or bright annealed. - "Hastelloy" is a registered trademark of Haynes International. --- *For specific thickness tolerances, testing certifications, or custom requirements, consult manufacturers' technical data sheets.*
