AISI 316 Stainless Steel Foil/Sheet
Available Configurations
Properties common to all products in this list
Key Features
AISI 316 Stainless Steel Foil (UNS S31600) is a thin-rolled austenitic stainless steel with 16-18% chromium, 10-14% nickel, and 2-3% molybdenum, offering enhanced pitting and crevice corrosion resistance compared with AISI 304 alongside good tensile strength, ductility, and biocompatibility:
Enhanced Pitting & Crevice Corrosion Resistance vs. AISI 304
The molybdenum content of AISI 316 Foil provides enhanced pitting and crevice corrosion resistance compared with AISI 304, making it the preferred foil grade for chloride-bearing environments.
Preferred Grade for Chloride-Bearing Environments
AISI 316 Foil's molybdenum content makes it the preferred choice for applications involving chloride-bearing environments, including marine, pharmaceutical, and chemical processing service.
Good Tensile Strength, Ductility & Biocompatibility
Good tensile strength, ductility, and biocompatibility together suit AISI 316 Foil to biomedical implant components where mechanical performance and tissue compatibility must be combined.
Reliable Performance from Cryogenic to Elevated Temperatures
AISI 316 Foil performs reliably from cryogenic to elevated service temperatures and retains mechanical integrity following welding when low-carbon grades are not available.
Suited to Vacuum System Foils
Chemical plant linings and vacuum system foils benefit from the combination of enhanced corrosion resistance and reliable mechanical performance characteristic of AISI 316 Foil.
Industrial Applications
AISI 316 Stainless Steel Foil is used across biomedical, marine, pharmaceutical, and vacuum technology sectors wherever chloride-bearing service environments demand enhanced corrosion resistance:
- ✦ Biomedical Implant Components
- Used in biomedical implant components, where good tensile strength, ductility, and biocompatibility together support reliable, long-term performance in contact with biological tissue.
- ✦ Cryogenic Containment Wraps
- Formed into cryogenic containment wraps, where reliable performance from cryogenic to elevated service temperatures ensures consistent mechanical and corrosion performance across the operating range.
- ✦ Chemical Plant Linings
- Used in chemical plant linings, where enhanced pitting and crevice corrosion resistance compared with AISI 304 ensures long-term durability in chloride-bearing chemical processing environments.
- ✦ Vacuum System Foils
- Applied as vacuum system foils, where the molybdenum-bearing composition's corrosion resistance and reliable mechanical integrity following welding support dependable vacuum system performance.
- ✦ Surface Treatment & Ultra-High Vacuum Research
- Used as a substrate for surface treatment evaluation, electrochemical corrosion studies, and ultra-high vacuum applications where the Mo-bearing austenitic composition is an experimental requirement.
