Stainless Steel Sheet for Kitchenware: 304/201 Selection and Four-Part List
In the kitchenware sector, we have organized four stainless steel parts: commonly used 304 / 201 / 316, thickness 0.3–5 mm.
Four Parts and Material List
| Part / Component | Recommended Grade | Size / Thickness | Surface | Composition | Standard |
|---|---|---|---|---|---|
| Cookware/Tableware/Ceramic Insulators | 304/316/201 | 3–1.2mm | 2B/Electrolytic/Polished | Food contact + acid + washing + dry-burn discoloration | GB/T 3280; GB 4806.9 |
| Cutting Tools/Slicing Blades | 420/440 | 1–5mm | Quench hardening + polishing | Edge wear + chipping + food acid corrosion | GB/T 1220; GB 4806.9 |
| Sinks/Laminated Countertops/Waterproof Baffles | 304/201 | 8–3.0mm | 2B/Brushed/Draping | Moisture + kitchen detergent + scratches + food contact | GB/T 3280; GB 4806.9 |
| Material Selection Tips | 304/201 | 5–2.0mm | Mirror/Sanding/Gold plating | Moisture + soapy water + scale + hand sweat | GB/T 3280 |
Interior isStandard ConfigurationCommon grades: 304 (3), 201 (3), 316 (1)
Material Types
- 304, 201, 316
- For acidic media, start with 316L; as concentration and temperature increase, upgrade to 904L / duplex (2/4 cycles).
- Thickness range 0.3–5 mm: thin sheet for formed parts (consider bending springback and deep drawing cracking), thick plate for welded structures (consider heat input and sensitization).
Frequently Asked Questions
What is the most commonly used stainless steel for household goods and kitchen utensils?
Top 4 across the full page: 304 (3), 201 (3), 316 (1). For specific parts, refer to the medium and temperature. For example, stainless steel countertops exposed to brine require 316L.
Where are problems most likely to occur?
Failure description, typically for "cooking pots/cups/thermos": food contact + salt/acid + washing + dry heating discoloration; recommended grades 304 / 316 / 201, thickness 0.3–1.2mm. For this scenario, we recommend specifying intermediate concentration, temperature and cleaning method at the design stage.
What thickness should I choose?
The thickness range in the list is 0.3–5 mm. For thin sheet, consider bending and surface finish; for thick plate, consider welding and structural strength. Even for the same location, values may vary by equipment manufacturer, so review drawings or operating conditions.
