AISI 316 Stainless Steel Coil
Available Configurations
Properties common to all products in this list
Key Features
AISI 316 Stainless Steel Coil (UNS S31600) is a molybdenum-bearing austenitic stainless steel in continuous coiled strip form, offering a well-established combination of high tensile strength, good corrosion resistance, and enhanced resistance to pitting and crevice corrosion compared with standard AISI 304:
Enhanced Pitting & Crevice Corrosion Resistance
With 16-18% chromium, 10-14% nickel, and 2-3% molybdenum, AISI 316 offers enhanced resistance to pitting and crevice corrosion compared with standard AISI 304, making it the standard choice wherever chloride exposure makes 304 inadequate.
Standard Choice for Marine, Chemical & Pharmaceutical Applications
AISI 316 is the standard choice for marine, chemical processing, and pharmaceutical applications where chloride exposure demands the molybdenum-bearing alloy's superior corrosion resistance.
Essentially Non-Magnetic with Predictable Work-Hardening (515-690 MPa)
In the annealed condition AISI 316 is essentially non-magnetic, with a tensile strength of approximately 515-690 MPa and elongation of 40%, and it work-hardens predictably during cold forming.
Coil Format Supports High-Volume Production
Coil form supports efficient high-volume production of formed components, strip linings, heat exchanger elements, and continuous precision parts for food-contact and process equipment.
High Tensile Strength with Good Corrosion Resistance
AISI 316's combination of high tensile strength and good corrosion resistance, enhanced by molybdenum, provides a well-established performance benchmark for chloride-resistant austenitic stainless applications.
Industrial Applications
AISI 316 Stainless Steel Coil is used across marine, chemical processing, and pharmaceutical sectors where chloride exposure makes standard AISI 304 inadequate:
- ✦ Formed Components for Marine & Chemical Processing
- Used in formed components for marine and chemical processing applications, where enhanced resistance to pitting and crevice corrosion compared with AISI 304 ensures long-term durability in chloride-rich environments.
- ✦ Strip Linings
- Applied as strip linings, where good corrosion resistance combined with predictable work-hardening during cold forming supports reliable lining performance in aggressive process environments.
- ✦ Heat Exchanger Elements
- Used in heat exchanger elements, where the molybdenum-bearing alloy's enhanced pitting and crevice corrosion resistance ensures long service life in chloride-exposed heat transfer applications.
- ✦ Continuous Precision Parts for Food-Contact & Process Equipment
- Formed into continuous precision parts for food-contact and process equipment, where the coil format's high-volume production efficiency supports cost-effective manufacture of corrosion-resistant components.
- ✦ Tribological Testing & Forming Behavior Research
- Used for tribological testing, surface treatment evaluation, and forming behavior studies in research and pilot production, where the molybdenum-bearing alloy composition is an experimental requirement.
