Stainless Steel Sheet Metal Plate 13×140mm Steel Spring Plate 0.3mm Thickness

The plate arrives at 13mm wide × 140mm long. You can trim the length with aviation snips or a rotary cut-off wheel and deburr the edge with a fine file. Width trimming is possible but requires a steady hand or a metal-cutting guide, as the 13mm dimension leaves little margin. If your slot is significantly narrower than 13mm, measure carefully before cutting to avoid wasting material.

At 0.3mm thickness, this plate is rated for light-to-medium spring loads — typically applications where the deflection is small (a few millimeters) and the load is distributed across the plate's width. Concentrated point loads or large deflection angles can exceed the elastic limit and cause permanent deformation. For heavier loads, a thicker gauge (0.5mm or above) is more appropriate.

Stainless steel resists rust and surface oxidation in most outdoor and humid environments without requiring paint or a protective coating. However, prolonged exposure to chloride-rich environments (such as coastal salt air or pool water) can cause surface pitting over time on standard 304-grade stainless. If your application involves direct saltwater contact, confirm the alloy grade before use or contact us for clarification.

Yes. The 0.3mm uniform thickness makes it a reliable shim for gap-setting tasks. You can stack multiple plates to achieve 0.6mm, 0.9mm, or other increments. Because the plates are flat and consistent in thickness, they produce repeatable results when used as feeler-gauge substitutes or fixed spacers in jigs, fences, and tool rests.

The 1-piece pack suits a single repair or prototype where you only need one plate. The 2-piece pack is useful when you need a matched pair — for example, two symmetrical spring tabs on either side of a latch. The 5-piece pack offers the lowest per-piece cost and is practical if you anticipate repeat repairs, want spares on hand, or are building multiple identical fixtures at once.

For straight cuts along the length, aviation snips (compound-action) produce clean edges with minimal burr. A rotary tool with a thin cut-off disc works well for cross-cuts or curved profiles. After cutting, deburr all edges with a fine-cut metal file or a deburring tool to remove sharp edges before handling. No welding, grinding, or heat treatment is required for basic trimming and fitting.

Yes. Stainless steel spring plate is galvanically compatible with stainless fasteners (screws, rivets, clips), minimizing the risk of galvanic corrosion at contact points. For adhesive bonding, clean the surface with isopropyl alcohol first; structural epoxies and cyanoacrylate adhesives both bond well to degreased stainless steel surfaces.
