AISI 304 Stainless Steel Coil
Available Configurations
Properties common to all products in this list
Key Features
AISI 304 Stainless Steel Coil (UNS S30400) is the most widely used austenitic stainless steel, supplied in a continuous coiled strip format that combines the well-established corrosion resistance of the 18% chromium-8-10% nickel composition with the processing efficiency of an uninterrupted high-volume supply format:
Excellent Balance of Mechanical Performance & Formability
With a tensile strength of 500-700 MPa, yield strength of 190-240 MPa, and elongation of approximately 40%, AISI 304 Coil offers an excellent balance of mechanical performance and formability suited to roll-forming, stamping, and progressive-die operations.
Well-Established Corrosion Resistance
The well-established corrosion resistance of the 18% chromium-8-10% nickel composition supports reliable performance in chemical processing, food-contact equipment, and general industrial fabrication applications.
Essentially Non-Magnetic Austenitic Structure
The face-centerd cubic austenitic structure is essentially non-magnetic in the annealed condition, a property relevant wherever magnetic interference must be minimized in formed components and assemblies.
Predictable Work-Hardening for Consistent Dimensional Control
AISI 304 work-hardens predictably during cold deformation, enabling consistent dimensional control across high-throughput fabrication runs where component-to-component repeatability is essential.
Continuous Coil Format for Processing Efficiency
The continuous coiled strip format delivers the processing efficiency of an uninterrupted high-volume supply, supporting roll-forming, stamping, and progressive-die operations without the handling interruptions associated with cut sheet.
Industrial Applications
AISI 304 Stainless Steel Coil is used across chemical processing, food-contact, automotive, and general industrial sectors as the most widely used austenitic stainless steel grade:
- ✦ Formed Components for Chemical Processing
- Used in formed components for chemical processing, where well-established corrosion resistance and predictable work-hardening during cold deformation ensure reliable performance and consistent dimensional control.
- ✦ Food-Contact Equipment
- Formed into food-contact equipment, where the well-established corrosion resistance of the 18-8 alloy system meets the hygiene and durability requirements of food processing environments.
- ✦ Automotive Assemblies
- Used in automotive assemblies, where the excellent balance of mechanical performance and formability supports efficient roll-forming, stamping, and progressive-die operations in high-volume production.
- ✦ General Industrial Fabrication
- Applied broadly in general industrial fabrication, where the continuous coil format's processing efficiency and predictable work-hardening behavior make AISI 304 the default choice for a wide range of formed component applications.
- ✦ Tribological Testing & Forming-Behavior Research
- Serves as a reproducible specification-controlled substrate in research for tribological testing, surface treatment evaluation, and forming-behavior studies across extended strip lengths.
