Stainless Steel Plate Sheet 0.01mm to 1mm, 100x100, 100x300, 200x300, 300x300mm

For precision shimming — such as adjusting bearing preload, aligning machine components, or calibrating small gaps — the 0.01mm to 0.05mm options function as shim stock. For structural gap-filling or backing plates where some rigidity is needed, 0.2mm to 0.5mm is a common range. If you are unsure, measure the gap with a feeler gauge first and select the matching thickness.

304 stainless steel has a typical tensile strength of 515–620 MPa and yield strength around 205 MPa, which is adequate for many light structural and mechanical uses. However, thin sheets (below 0.3mm) are not intended for load-bearing roles — they are better suited for shims, liners, and decorative applications. For structural plate work, the 0.5mm–1mm range provides more rigidity.

304 stainless steel forms a passive chromium-oxide layer that resists rust and staining in most indoor and sheltered outdoor environments. It performs well against mild acids, food contact, and humidity. However, it is not ideal for prolonged exposure to chloride-rich environments (such as saltwater or de-icing salts) — 316-grade stainless would be more appropriate in those conditions.

Yes. 304 stainless steel is compatible with laser cutting, waterjet cutting, plasma cutting, TIG and MIG welding, and CNC milling. Thinner sheets (0.01–0.1mm) are best cut with shears, a craft knife, or laser to avoid distortion. For welding, use ER308L filler wire and back-purge where possible to prevent oxidation on the reverse side.

The 100×100mm size suits small components, test coupons, and single-part repairs. The 100×300mm strip format works well for brackets, rails, and elongated parts. The 200×300mm sheet covers medium panel work and enclosure blanks. The 300×300mm sheet is the largest option and is suited for larger backing plates, decorative panels, or projects requiring multiple smaller pieces cut from one sheet.

If you need a single piece for a repair or prototype, choose Qty 1. For matched pairs or assemblies requiring identical shims on both sides, Qty 2 is efficient. Qty 5 and Qty 10 packs offer a lower per-piece cost and are practical for small production runs, classroom use, or keeping spares on hand. All pieces in a pack are the same size and thickness.

The mill finish (2B equivalent) is a smooth, matte-reflective surface that works well as a decorative inlay, trim piece, or wear surface in furniture and cabinetry. It can be polished to a brighter finish with abrasive pads or buffing compounds, or brushed to a directional grain. It accepts adhesive bonding and most metal coatings without special pre-treatment in typical workshop conditions.
