AISI 316 Stainless Steel Disk
Available Configurations
Properties common to all products in this list
Key Features
AISI 316 Stainless Steel Disk (UNS S31600) is a precision-cut austenitic stainless steel component with 16-18% chromium, 10-14% nickel, and 2-3% molybdenum, combining high corrosion resistance, mechanical strength, and dimensional stability in a ready-to-use circular geometry:
Substantially Improved Pitting & Crevice Corrosion Resistance
The molybdenum addition provides substantially improved resistance to pitting and crevice corrosion compared with AISI 304, making this disk suitable for aggressive chemical, marine, and high-vacuum service environments.
Dimensional Accuracy for Precision Instrumentation
Dimensional accuracy and material purity are critical in precision instrumentation, chemical processing equipment, and biomedical device components where this disk format is used.
High Corrosion Resistance Across Aggressive Environments
High corrosion resistance suits this disk to sealing plates in high-pressure pumps and flanges for pharmaceutical reactors exposed to aggressive process conditions.
Suited to Vacuum System Hardware
The combination of dimensional stability and corrosion resistance supports use in vacuum system hardware and substrates for thin-film deposition systems where surface and dimensional integrity are critical.
Deliberate Mo-Bearing Alloy Variable for Research
AISI 316 Disk's molybdenum-bearing composition serves as a deliberate experimental variable in tribological studies, surface modification experiments, and electrochemical characterization research.
Industrial Applications
AISI 316 Stainless Steel Disk is used across precision instrumentation, chemical processing, biomedical, and vacuum technology sectors where dimensional accuracy and material purity are critical:
- ✦ Sealing Plates in High-Pressure Pumps
- Used as sealing plates in high-pressure pumps, where substantially improved resistance to pitting and crevice corrosion compared with AISI 304 ensures reliable sealing performance under demanding pressure and chemical conditions.
- ✦ Flanges for Pharmaceutical Reactors
- Applied as flanges for pharmaceutical reactors, where high corrosion resistance and dimensional stability support reliable, contamination-free sealing in pharmaceutical processing equipment.
- ✦ Substrates for Thin-Film Deposition Systems
- Used as substrates for thin-film deposition systems, where dimensional accuracy and material purity are critical to achieving consistent, reproducible deposition outcomes.
- ✦ Biomedical Device Components & Vacuum System Hardware
- Applied in biomedical device components and vacuum system hardware, where dimensional accuracy and corrosion resistance are both critical to reliable, long-term device performance.
- ✦ Tribological & Electrochemical Characterization Research
- Serves in tribological studies, surface modification experiments, and electrochemical characterization where the Mo-bearing alloy composition is a deliberate experimental variable.
