InsideStandard ConfigurationCommon grades: 304 (3), 201 (3), 316 (1)
Material Types
- 304, 201, 316
- Start with 316L in acidic media; as concentration and temperature increase, move up to 904L / duplex (2/4 hits).
- Thickness range 0.3–5 mm: thin sheets are for formed parts (consider springback in bending and cracking in deep drawing), thick plates are for welded structures (consider heat input and sensitization).
FAQ
Which stainless steel is most used for household items and cookware?
By total page count, the top 4 are: 304 (3), 201 (3) and 316 (1). For specific parts, refer to the medium and temperature; for example, stainless steel countertops require 316L when exposed to salt water.
Which part is most prone to problems?
Failure description, typically for "pots/cups/thermal bottles": food contact + salt/acid + cleaning + dry heating causes discoloration; Recommended grades 304 / 316 / 201, thickness 0.3–1.2mm. This scenario recommends specifying medium concentration, temperature and cleaning method during the design phase.
What thickness should I select?
The thickness range in the list is 0.3–5 mm. For thin sheets, consider bending and surface finish; for thick plates, welding and structural strength. Values may vary by equipment manufacturer for the same location; check your drawing or operating conditions.
