This listing is designed for makers, fabricators, and home workshop enthusiasts who need a reliable, ready-to-use metal blank without the guesswork.\u003c\/p\u003e\n    \u003cp\u003eEach pack contains 3 round discs cut from 304 stainless steel with a mirror-polished finish. The discs measure 60 mm (approx. 2.36 in) in diameter and 3 mm (approx. 0.12 in) in thickness, offering a solid cross-section suitable for moderate structural and decorative applications. The 304 alloy composition (18% chromium, 8% nickel) delivers strong corrosion resistance in both indoor and outdoor environments.\u003c\/p\u003e\n    \u003cp\u003eTypical use cases include decorative inlays and furniture accents, custom gaskets and spacer blanks for light-duty mechanical assemblies, and craft or jewellery-making bases where a mirror-finish stainless steel round disc is required.
