Ion Implanted AISI 316 Stainless Steel Foil (Light Tight)
Available Configurations
Properties common to all products in this list
Key Features
Ion Implanted AISI 316 Stainless Steel Foil (Light Tight) (UNS S31600) is a molybdenum-bearing austenitic stainless steel foil that combines ion implantation surface modification with a pinhole-free light-tight structure, providing enhanced surface hardness and corrosion resistance alongside complete optical opacity:
Enhanced Surface Hardness & Corrosion Resistance Alongside Complete Optical Opacity
This foil combines ion implantation surface modification with a pinhole-free light-tight structure, providing enhanced surface hardness and corrosion resistance alongside complete optical opacity.
Improved Microhardness, Pitting Resistance & Corrosion Behavior at Low Process Temperatures
Ion implantation introduces ionic species into the near-surface layer at low process temperatures, improving microhardness, pitting resistance, and corrosion behavior without sensitizing the substrate or altering its bulk properties.
Suited to Light-Tight Enclosures Requiring Surface-Enhanced Durability & Optical Isolation
This foil is suitable for light-tight enclosures in medical devices, vacuum systems, and sensitive optoelectronic assemblies where both surface-enhanced durability and reliable optical isolation are simultaneously required.
Bulk Properties Preserved by Low-Temperature Implantation Process
The low process temperature of ion implantation avoids sensitizing the substrate or altering its bulk properties, ensuring the light-tight foil retains the full mechanical performance of standard 316 alloy.
Suited to MRI-Compatible & Optoelectronic Isolation Applications
MRI-compatible optical shielding components and optoelectronic isolation barriers benefit from this foil's unique combination of enhanced surface properties and complete light exclusion.
Industrial Applications
Ion Implanted AISI 316 Stainless Steel Foil (Light Tight) is used across medical device, vacuum system, and optoelectronic sectors where surface-enhanced durability and reliable optical isolation are simultaneously required:
- ✦ Light-Sensitive Biosensor Housings
- Used in light-sensitive biosensor housings, where enhanced surface hardness and corrosion resistance from ion implantation combine with complete optical opacity to protect sensitive biosensor components.
- ✦ MRI-Compatible Optical Shielding Components
- Formed into MRI-compatible optical shielding components, where the substrate's unaltered bulk properties ensure compatibility with MRI environments while the surface modification enhances durability.
- ✦ Optoelectronic Isolation Barriers in Precision Analytical & Medical Instrumentation
- Used as optoelectronic isolation barriers in precision analytical and medical instrumentation, where surface-enhanced durability and reliable optical isolation are simultaneously required for dependable instrument performance.
- ✦ Ion Implantation Effects & Medical Device Surface Engineering Research
- Supports investigations into ion implantation effects on surface properties in the context of light-tight barrier applications and advanced medical device surface engineering.
