AMAT 3880-01288
Product Name: Flat Washer, Precision Stainless Steel
Product Description: A high-precision, flat washer engineered for use in ultra-high vacuum (UHV) assemblies. It provides uniform load distribution, prevents galling, and maintains precise spacing between critical components.
Technical Specifications:
- Material: 316L stainless steel (vacuum arc remelted)
Detailed content
- Inner Diameter: 0.344 inches (8.74 mm)
- Outer Diameter: 0.625 inches (15.88 mm)
- Thickness: 0.056 to 0.071 inches (1.42 to 1.80 mm)
- Surface Finish: Electropolished (Ra < 0.8 μm)
- Hardness: Rockwell B 80-90
- Cleanliness: UHV cleaned, double-bagged
- Leak Rate: < 1 x 10⁻⁹ atm·cc/s He
Key Features:
- Precision dimensional tolerances for consistent spacing
- Corrosion-resistant in harsh process gas environments
- Low outgassing for UHV compatibility
- Smooth surface prevents particle generation
