AISI 410 Stainless Steel Foil (Light Tight)
Available Configurations
Properties common to all products in this list
Key Features
AISI 410 Stainless Steel Foil (Light Tight) (UNS S41000) is a martensitic chromium stainless steel foil with 11.5-13.5% chromium, manufactured to a pinhole-free surface that blocks all external light transmission while delivering high mechanical strength and wear resistance after appropriate heat treatment:
Blocks All External Light Transmission
Manufactured to a pinhole-free surface, this foil blocks all external light transmission, providing a reliable optical barrier alongside its mechanical strength and wear resistance.
High Mechanical Strength & Wear Resistance After Heat Treatment
High mechanical strength and wear resistance after appropriate heat treatment distinguish this foil from softer light-tight alternatives, supporting use in applications where the barrier must also resist mechanical wear.
Moderate Corrosion Resistance in Mildly Aggressive Environments
Moderate corrosion resistance in mildly aggressive service environments, combined with thermal stability, makes this foil suitable for precision optical devices and hermetic sealing systems.
Maintains Hardness Following Thermal Exposure
The ability to maintain hardness following thermal exposure ensures the light-tight barrier retains its wear resistance properties even after repeated thermal cycling in service.
Suited to Light Ingress-Sensitive Instrument Enclosures
This foil suits instrument enclosures where light ingress would compromise function, combining complete light exclusion with the wear resistance needed for durable mechanical performance.
Industrial Applications
AISI 410 Stainless Steel Foil (Light Tight) is used across precision optical, hermetic sealing, and emission control sectors where light ingress would compromise function:
- ✦ Precision Light-Blocking Shims in Measurement Instruments
- Used as precision light-blocking shims in measurement instruments, where the pinhole-free surface blocks all external light transmission and high mechanical strength after heat treatment ensures dimensional stability under load.
- ✦ Optical Enclosure Linings
- Formed into optical enclosure linings, where moderate corrosion resistance combined with thermal stability supports reliable long-term performance in precision optical devices.
- ✦ Wear-Resistant Sealing Strips in Light-Sensitive Manufacturing Environments
- Used as wear-resistant sealing strips in light-sensitive manufacturing environments, where high mechanical strength and wear resistance after heat treatment ensure durable sealing performance under repeated mechanical contact.
- ✦ Catalyst Carrier Assemblies in Emission Control Systems
- Applied in catalyst carrier assemblies for emission control systems, where the foil's ability to maintain hardness following thermal exposure ensures reliable performance under sustained operating temperatures.
- ✦ Heat Treatment Effects & Optical Opacity Research
- Supports investigations into heat treatment effects on toughness and surface engineering approaches to maintaining optical opacity under thermal cycling.
