AISI 316L Stainless Steel Foil
Available Configurations
Properties common to all products in this list
Key Features
AISI 316L Stainless Steel Foil (UNS S31603) is a low-carbon molybdenum-bearing austenitic stainless steel foil with carbon restricted to 0.03 wt% maximum, combining the enhanced pitting and crevice corrosion resistance of the 316 alloy system with reliable weld integrity and freedom from sensitization risk:
Reliable Weld Integrity & Freedom from Sensitization Risk
Carbon restricted to 0.03 wt% maximum combines the enhanced pitting and crevice corrosion resistance of the 316 alloy system with reliable weld integrity and freedom from sensitization risk.
Reliable Performance from Cryogenic to ~870 °C
AISI 316L Foil performs consistently from cryogenic service to approximately 870 °C continuous use, and maintains mechanical integrity following welding.
Preferred 316-Family Foil Grade for Post-Fabrication Thermal Exposure
AISI 316L Foil is the preferred 316-family foil grade wherever post-fabrication thermal exposure is expected, ensuring weld integrity is not compromised by subsequent thermal cycling.
Suited to Cleanroom Enclosures & Vacuum Chamber Linings
Cleanroom enclosures, vacuum chamber linings, and diaphragm seals benefit from the combination of low-carbon weld integrity and enhanced corrosion resistance characteristic of AISI 316L Foil.
Biocompatible System Parts
Biocompatible system parts rely on AISI 316L Foil's combination of corrosion resistance, biocompatibility, and reliable mechanical performance following welding or thermal processing.
Industrial Applications
AISI 316L Stainless Steel Foil is used across cleanroom, vacuum technology, MEMS, and biomedical sectors wherever post-fabrication thermal exposure is expected:
- ✦ Cleanroom Enclosures
- Used in cleanroom enclosures, where freedom from sensitization risk combined with enhanced pitting and crevice corrosion resistance ensures reliable performance in controlled contamination environments.
- ✦ Vacuum Chamber Linings
- Formed into vacuum chamber linings, where reliable performance from cryogenic service to approximately 870 °C continuous use supports demanding vacuum system thermal requirements.
- ✦ Diaphragm Seals
- Used in diaphragm seals, where mechanical integrity following welding ensures reliable sealing performance even in assemblies that require post-fabrication joining operations.
- ✦ Precision Shielding Components & Biocompatible System Parts
- Applied in precision shielding components and biocompatible system parts, where the preferred 316-family status of 316L for post-fabrication thermal exposure ensures dependable long-term performance.
- ✦ MEMS Prototyping & Laser Processing Research
- Supports MEMS prototyping, precision sample mounting, laser processing studies, and surface ablation experiments across optics, materials science, and thermal engineering disciplines.
