Stainless Steel Round Blank Discs — Precision Laser Cut, A2 Grade, Ready to Fabricate

Whether you're shimming a bearing, crafting a custom sign, or cutting a gasket to spec, finding a flat, true-round metal blank in exactly the right size is often the hardest part of the job. Machinists, fabricators, hobbyists, and DIYers who need a reliable stainless steel round blank disc without the hassle of cutting raw sheet stock will find these laser-cut circles a practical, time-saving solution.

Each disc is a single solid round plate cut from A2 (304) stainless steel sheet. Diameters range from 50mm (≈2") to 400mm (≈15¾"), and thickness options span 0.5mm (≈0.020") to 10mm (≈3/8"). The laser-cutting process delivers a clean, consistent circular profile with tight dimensional accuracy across the full size range.

Typical applications include use as shim stock and spacers in mechanical assemblies, blanks for custom engraving or etching projects, backing plates and cover discs in construction and joinery, and decorative metalwork in furniture and interior design. The corrosion-resistant surface also makes these discs a practical choice for food-adjacent fixtures, outdoor signage, and light marine fittings.

🔵 Compatibility Note: These are solid blank discs with no pre-drilled holes. They are compatible with any application requiring a flat, round stainless steel plate. Drilling, tapping, or further machining is the buyer's responsibility. Verify diameter and thickness against your project specs before ordering.
⚠️ Size Tip: Laser-cut edges are generally clean but may have minor oxidation or slight roughness depending on thickness. Light deburring is recommended for precision-fit applications. If you need a specific tolerance, contact us to confirm before ordering.

✅ Key Features of These Stainless Steel Round Blank Discs

  • 🎯Laser-Cut Precision — Each disc is cut to a consistent circular profile, making these stainless steel laser cut round blanks suitable for applications where a true round shape matters, such as gaskets, shims, and decorative inlays.
  • 🦀A2 (304) Corrosion Resistance — The 18/8 chromium-nickel composition provides solid resistance to rust and oxidation, making these discs a dependable choice for outdoor fixtures, damp environments, and food-contact applications.
  • 📐Wide Size Range — Available in diameters from 50mm (≈2") to 400mm (≈15¾") and thicknesses from 0.5mm to 10mm, covering a broad spectrum of DIY fabrication and engineering blank needs in a single product line.
  • 🔧Machinable & Weldable — A2 stainless steel can be drilled, tapped, milled, and TIG/MIG welded, so these solid round plate blanks serve as a versatile starting point for custom parts and prototypes.
  • ✂️Solid Through-Section — Unlike stamped or formed parts, these are cut from flat sheet stock, giving a uniform thickness across the entire face — important for applications like bearing shims or precision spacers.
  • 📦Sold by the Piece — Order exactly what you need — no minimum pack sizes. Ideal for prototyping, one-off repairs, or topping up stock without committing to bulk quantities of stainless steel round discs.

❓ Frequently Asked Questions

How do I choose the right diameter and thickness for my project?

Match the diameter to your mounting hole or coverage area. For reference, 100mm is approximately 3.94" and 200mm is approximately 7.87". For thickness, thinner discs (0.5–1mm) are generally used for shims, gaskets, and decorative work, while thicker discs (3mm and above) are typically chosen for structural or load-bearing applications. When in doubt, order one size up — it's easier to trim than to add material.

How strong are these stainless steel discs?

A2 (304) stainless steel typically has a tensile strength of around 515 MPa and a yield strength of approximately 205 MPa. Actual load capacity depends on the diameter, thickness, and how the disc is supported or fastened in your application. For critical structural uses, consult an engineer to confirm suitability.

Are these discs suitable for outdoor or marine use?

A2 stainless steel offers good corrosion resistance and is generally suitable for outdoor environments including light rain exposure and moderate humidity. For highly aggressive marine or coastal environments with prolonged saltwater exposure, A4 (316) grade is typically recommended instead. For occasional outdoor use, A2 performs well in most climates.

What is A2 stainless steel and how does it compare to other grades?

A2 stainless steel is equivalent to 304 grade — the most widely used stainless alloy. It contains approximately 18% chromium and 8% nickel, giving it good corrosion resistance, weldability, and formability. It is generally preferred over A4/316 for cost-sensitive indoor and light outdoor applications where extreme chemical or saltwater resistance is not required.

Can I drill, cut, or weld these discs?

Yes. A2 stainless steel is machinable with standard HSS or carbide tooling. Use cutting fluid and moderate speeds to avoid work-hardening the surface. These discs are also weldable using TIG or MIG processes with appropriate 308L or 304 filler wire. Always clamp securely and use appropriate PPE when machining stainless steel.

What finish do the laser-cut edges have?

The discs are laser cut, which typically produces a clean, precise edge with minimal burring. The flat faces generally retain the mill finish of the source sheet. Light deburring or sanding may be needed depending on your application — particularly for skin-contact or precision-fit uses. Contact us if you need a specific edge or surface finish.

Are these discs sold individually or in packs?

Each listing is for 1 piece per order. Select your diameter and thickness from the variant options above, then adjust the quantity at checkout if you need multiple pieces of the same size. There is no minimum order quantity.
