4 Pcs Stainless Steel Blank Round Disc 304 Grade Metal Sheet Plate Dia 34mm

Each disc measures 34 mm (approximately 1.34 inches) in diameter and 0.5 mm (approximately 0.020 inches) in thickness. These dimensions are consistent across all 4 pieces in the pack.

304 stainless steel provides solid corrosion resistance in most indoor environments and moderate outdoor conditions. Prolonged exposure to saltwater, chlorine, or harsh industrial chemicals may cause surface staining over time. For marine or highly corrosive environments, 316-grade stainless steel is generally recommended.

Yes. At 0.5 mm thickness, these discs are compatible with metal hand stamps, rotary engravers, and laser markers calibrated for stainless steel. For deep hand stamping, a steel bench block and firm mallet strikes are recommended to achieve clean impressions.

The edges are finished to minimize burrs. However, as with any cut metal part, we recommend a quick inspection and light sanding with fine-grit paper (400+ grit) if the discs will be used in wearable jewelry or handled frequently by end users.

304 stainless steel is generally considered non-magnetic in its annealed state, though it may exhibit weak magnetism after cold working or cutting. If strict non-magnetic properties are required, please contact us to confirm suitability for your application.

Yes, the flat, consistent geometry makes these discs suitable for use as prototype gaskets or shims in light-duty applications. For critical sealing or load-bearing uses, verify the thickness tolerance meets your engineering requirements before committing to a design.
