SS 304 Coils (UNS S30400) combine an 18–20% chromium and 8–10.5% nickel composition with the versatility needed for demanding fabrication workflows. Supplied in coil form, this grade allows manufacturers to feed material into stamping lines, blanking operations and roll-forming processes, helping streamline production of components, enclosures and custom-fabricated parts.

Hot-rolled coils feature a mill finish and are used where the specified thickness and surface condition meet fabrication requirements.
Cold-rolled coils offer a smoother surface and controlled thickness for precision fabrication and formed components.
These coils have a smooth, moderately reflective finish suitable for industrial components, equipment panels and general fabrication.
Bright Annealed (BA) coils feature a smooth, bright surface for applications requiring a more reflective finish.
The alloy composition supports corrosion resistance in many atmospheric and general industrial environments.
SS 304 can be formed into a range of components, although work hardening increases strength during cold deformation.
The grade is generally weldable using suitable procedures. Heat tint and contamination should be addressed through appropriate post-weld cleaning where required.
Available finishes may support different requirements for appearance, fabrication and subsequent processing.
| Industry | Typical Applications |
|---|---|
| Food Processing | Equipment panels, work surfaces and fabricated components |
| Commercial Kitchens | Countertops, equipment housings and selected kitchen components |
| Chemical Processing | Tanks, covers and components for compatible process environments |
| Pharmaceutical Equipment | Fabricated enclosures and equipment parts where the specified finish is suitable |
| Automotive | Formed trim, brackets and selected fabricated components |
| General Engineering | Covers, housings, sheet-metal parts and machine components |
| Construction | Interior panels, architectural components and fabricated fittings |
| Industrial Manufacturing | Pressed parts, formed sections and general-purpose components |
Metalloy Steel can discuss documentation and inspection requirements for SS 304 Coils, subject to availability and the agreed purchase specification. Buyers should identify any mandatory documentation or testing at the enquiry stage.
EN 10204 Type 3.1 documentation, where available and agreed for the supply.
Review of the material certificate or testing as specified.
Tensile, yield, elongation and hardness checks where required by the governing specification.
Verification of coil thickness and width against the order requirements.
Assessment of finish and visible surface condition against the agreed requirements.
Can be discussed when specified in the purchase order and confirmed before supply.
ASTM A240/A240M specifies stainless steel plate, sheet and strip requirements, while ASTM A480/A480M covers general requirements for flat-rolled stainless steel products. Confirm the applicable standards for your order.
Available dimensions depend on the supply range and required specification. Share the required thickness, width, finish and quantity with Metalloy Steel to confirm availability.
Yes. SS 304 is generally suitable for common welding and forming processes when the correct procedures are used. It work-hardens during cold forming, so forming method, tooling and material condition should be considered.
You can specify the required finish, such as 2B or BA, in your enquiry. Availability and conformity to the requested finish should be confirmed before ordering.
