301 Stainless Steel Sheet Strip 100×500mm — Choose Thickness 0.05mm to 3mm

For shims and gap-filling, 0.05–0.20mm (0.002"–0.008") is typically sufficient. For spring clips and flexible brackets, 0.25–0.50mm generally works well. For structural panels or wear plates, 0.60mm and above is recommended. When in doubt, start thinner — you can always stack shims to reach your target gap.

Divide the mm value by 25.4. Quick reference:

• 0.10mm ≈ 0.004" (4 thou)
• 0.50mm ≈ 0.020" (20 thou)
• 1.00mm ≈ 0.039"
• 2.00mm ≈ 0.079"
• 3.00mm ≈ 0.118"

These are commonly referenced as "shim stock" or "feeler gauge" thicknesses in US machining and fabrication contexts.

301 stainless contains slightly less nickel and chromium than 304, which gives it a higher work-hardening rate and greater spring-back elasticity. It is generally preferred for spring strips, retaining clips, and flexible components where 304 would be too soft or prone to permanent deformation. For purely structural or food-contact applications, 304 is typically the better choice.

301 stainless steel offers good corrosion resistance for most indoor and light outdoor applications — including HVAC enclosures, automotive underbody repairs, and general workshop fabrication. In highly corrosive environments such as coastal salt air, chemical splash zones, or submerged applications, 316 stainless is generally a better choice. For typical outdoor DIY use, 301 performs well.

Thinner variants (0.05–0.30mm) can generally be cut with heavy-duty scissors, a utility knife and straightedge, or tin snips, and bent by hand or over a straight edge. Thicker variants (0.50mm and above) typically require metal shears, a nibbler, or an angle grinder with a cutting disc for clean results. For precise bends in thicker stock, a bench vise or sheet metal brake is recommended. Always wear cut-resistant gloves.

301 stainless steel in annealed condition typically has a tensile strength of around 515 MPa (≈75,000 psi). Work-hardened grades can reach significantly higher values. Actual load capacity in your application depends on thickness, unsupported span, and loading direction.

Yes. 301 stainless is generally weldable using TIG or MIG processes. Use 308L filler rod for best corrosion resistance at the weld zone. Avoid prolonged heat input on thin gauges (≤0.20mm) as warping is likely. Soldering is possible with appropriate stainless flux, though mechanical fastening or adhesive bonding is often more practical for thin sheet applications.

The 100mm × 500mm (≈3.94" × 19.69") size suits most shim blanks, small gaskets, spring strips, and repair patches. If your project requires a larger panel, contact us — we may be able to source custom-cut sizes. Alternatively, multiple pieces can be overlapped and fastened for larger coverage areas.
