A2 Stainless Steel Flat Bar Metal Strip Sheet Foil Band Roll 0.3mmx5mmx2m

A2 is the ISO designation for Grade 304 stainless steel, one of the most widely used stainless alloys. It contains approximately 18% chromium and 8% nickel, which gives it strong resistance to rust and oxidation. Unlike carbon steel, it does not require painting or galvanizing to resist corrosion in typical indoor and outdoor environments.

Yes. At 0.3 mm thickness, this strip can be cut cleanly with heavy-duty scissors, aviation tin snips, or a sharp utility knife scored against a metal ruler. A fine-tooth hacksaw or rotary tool with a cutting disc also works well for straight cuts. Deburr the cut edge with a fine file or sandpaper for a clean finish.

A2 / 304 stainless steel performs well in most outdoor environments with moderate humidity and mild chemical exposure. However, it is not recommended for direct saltwater or marine environments, where chloride-induced pitting can occur. For marine or coastal applications, A4 / Grade 316 stainless steel is the appropriate choice.

Yes. The 0.3 mm thickness makes this strip flexible enough to bend by hand to gentle curves. For tighter bends, use smooth-jaw pliers or a bending jig to avoid kinking. Grade 304 in the annealed condition has good ductility, so it will not crack under moderate forming as long as the bend radius is at least 2–3 times the strip thickness.

Under normal indoor conditions, A2 / 304 stainless steel will not rust. In environments with prolonged exposure to chlorides, acids, or standing water, surface discoloration or pitting is possible over time. Wiping the strip clean and dry after exposure to moisture or chemicals will extend its appearance and service life significantly.

Common applications include: shim stock for machinery and equipment alignment, edge banding or inlay strips in woodworking and furniture, flexible retaining straps or spring clips, cable management bands, decorative metal trim, and repair patches for thin sheet metal. The 5 mm width is particularly suited to narrow-channel or tight-clearance applications.

Choose 0.3 mm when you need a strip that can be cut with hand tools, bent without a press brake, or used as shim stock where minimal added thickness matters. If your application requires structural load-bearing, resistance to deformation under pressure, or welding, a thicker flat bar (1 mm or above) would be more appropriate.
