Stainless Steel Sheets for Kitchenware: 304/201 Selection and a Four-Part List
In our kitchenware range, we have organized four stainless steel categories: the common 304 / 201 / 316, with thickness from 0.3–5 mm.
The Four Parts and Material List
| Part / Component | Recommended Grade | Size / Thickness | Surface | Configuration | Standards |
|---|---|---|---|---|---|
| Cookware / dishes / ceramic insulators | 304/316/201 | 3–1.2mm | 2B / electrolytic / polished | Food contact + acid + cleaning + discoloration from dry burning | GB/T 3280; GB 4806.9 |
| Cutting tools / chopping blades | 420/440 | 1–5mm | Cold hardened + polished | Edge wear + chipping + corrosion by food acids | GB/T 1220; GB 4806.9 |
| Washing sinks / laminated worktops / splash guards | 304/201 | 8–3.0mm | 2B / brushed / rolled | Moisture + dishwashing liquid + scratches + food contact | GB/T 3280; GB 4806.9 |
| Material Selection Tips | 304/201 | 5–2.0mm | Mirror / brushed / gold-plated | Moisture + soap solution + scale + hand sweat | GB/T 3280 |

Material Types
- 304, 201, 316
- Start with 316L in acidic media, and step up to 904L / duplex as concentration and temperature increase (2/4 clicks).
- Thickness range 0.3–5 mm: thin sheets for formed parts (consider bending springback and deep-drawing cracking), thick plates for welded structures (consider heat input and sensitization).
FAQ
Which type of stainless steel is most used in household goods and kitchenware?
Based on total pages, the top four are: 304 (3), 201 (3), and 316 (1). For specific parts, refer to the medium and temperature; for example, stainless steel worktops require 316L when exposed to salt water.
Which part is most prone to problems?
Failure description, usually for "cookware / cups / insulated water bottles": food contact + salt / acid + cleaning + dry burning causes discoloration; recommended grades 304 / 316 / 201, thickness 0.3–1.2mm. This scenario recommends defining the medium concentration, temperature and cleaning method during the design stage.
What thickness should I choose?
The thickness range in the list is 0.3–5 mm. For thin sheets, consider bending and surface finish; for thick plates, consider welding and structural strength. Values may vary by equipment manufacturer for the same application; refer to your drawing or operating conditions.
