Hobbyists, machinists, and fabricators who need ultra-thin 304 stainless steel sheet metal plate in controlled dimensions often waste hours sourcing material that arrives warped, oversized, or mislabeled. This listing solves that problem with a ready-to-use 200 × 300 mm (approx. 7.87 × 11.81 in) panel available in 16 thickness steps from 0.02 mm to 0.4 mm.\u003c\/p\u003e\n\u003cp\u003eEach piece is cut from 304-grade austenitic stainless steel — a chromium-nickel alloy containing approximately 18% chromium and 8% nickel — and supplied as a flat foil sheet. Sheet dimensions are 200 mm × 300 mm (7.87 in × 11.81 in); thickness options span 0.02 mm, 0.025 mm, 0.03 mm, 0.04 mm, 0.05 mm, 0.06 mm, 0.07 mm, 0.09 mm, 0.1 mm, 0.12 mm, 0.15 mm, 0.18 mm, 0.2 mm, 0.25 mm, 0.3 mm, and 0.4 mm.\u003c\/p\u003e\n\u003cp\u003eTypical applications include precision shim stacks under machine tool slides, custom gaskets for plumbing or HVAC fittings, heat-shield liners in electronics enclosures, and decorative inlay work in woodworking or leathercraft. The consistent gauge makes it equally useful as a feeler-gauge substitute, a stencil blank, or a thin backing plate in DIY repair projects where stainless steel sheet metal plate must resist moisture and mild chemicals without coating.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"hdiy-compat\"\u003e\n\u003cspan class=\"hdiy-compat-icon\"\u003e🔧\u003c\/span\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Suitable for use with standard metal snips, laser cutters, waterjet cutters, and bench shears.
