Stainless Steel Flat Plate Square Sheet Board Size: 15 "x 15" x 1/8 "

The specific grade is listed in the variant options. Common grades for flat plate stock in this thickness range include 304 and 316. Grade 304 is suitable for most indoor and general outdoor applications, while 316 offers enhanced resistance to chlorides and salt environments. If your project requires a specific grade, please check the variant selector or contact us to confirm before ordering.

Yes. At 1/8" (3.175 mm) thickness, this plate can be cut using an angle grinder with a stainless-rated cutting disc, a plasma cutter, a jigsaw with a bi-metal blade, or a cold saw. Avoid using carbon steel blades without a stainless-rated coating, as cross-contamination can cause surface rust at cut edges.

Stainless steel flat plate resists oxidation and surface rust in most outdoor and humid conditions without additional coating. For environments with prolonged salt water or chemical exposure, a 316-grade variant is recommended. Bare cut edges should be passivated or sealed if used in highly corrosive settings.

Yes. This flat plate is compatible with TIG and MIG welding using stainless steel filler wire matched to the base metal grade. Use back-purging for full-penetration welds on food-grade or sanitary applications. Avoid using carbon steel wire or electrodes, which can compromise corrosion resistance at the weld zone.

The 15"×15" format is ideal when your finished part fits within a roughly 14"×14" usable area after accounting for saw kerf and edge cleanup. If your part requires a larger blank, consider ordering a bigger sheet and cutting down, or contact us about custom cut sizes. For small brackets, mounting plates, or patch panels, this size typically eliminates the need for further trimming.

Flat plate stock at 1/8" thickness is generally rigid enough to arrive flat under normal shipping conditions. Minor surface variation of typically less than 1–2 mm across the face is within standard mill tolerance for this gauge. If your application requires a precision-flat surface, plan for a light pass on a surface grinder or milling machine after receipt.

Stainless steel is widely used in food service environments. However, food-safety compliance depends on the specific grade, surface finish, and any post-processing (welding, cutting) performed. For food-contact applications, confirm the grade with us and ensure all cut edges and welds are properly finished and passivated per applicable food safety standards.
