Makers, fabricators, and engineers working on shims, gaskets, heat shields, or precision enclosures need material that holds tight tolerances without warping or surface defects. These 304 stainless steel foil sheets are stocked specifically for that gap.\u003c\/p\u003e\n    \u003cp\u003eEach sheet is cut from 304-grade stainless steel — an austenitic alloy with a chromium content of approximately 18% and nickel content of approximately 8%, giving it a bright mill finish and consistent mechanical properties across the sheet. Available thicknesses range from 0.05 mm (~0.002 in) to 0.5 mm (~0.020 in), and sheet sizes include 305 mm × 1000 mm (~12 in × 39 in) and 200 mm × 3000 mm (~7.9 in × 118 in).\u003c\/p\u003e\n    \u003cp\u003eTypical applications include: thin stainless steel shim stock for machinery alignment, stainless foil for DIY heat shields and exhaust wraps, precision gasket blanks for fluid systems, and craft or art projects requiring a corrosion-resistant metal substrate.
