Stainless Steel Sheets for the Textile Industry: 316L/304 Selection and 7 Parts List
In the textile industry, we have organized 7 parts using stainless steel: typically 316L / 304 / 321, with thicknesses from 1–400 mm.
Seven-Part List and Material Options

Consider Application Specifics
- What are the most common grades in this industry? (316L, 304, 321)
- Common corrosion sources: pitting and crevice corrosion (mentioned in 5/7 cases).
- Welded components should be monitored for sensitization and chloride-induced stress corrosion cracking (mentioned in 3/7 cases).
- Thickness range 1–400 mm: thin sheets are mostly formed parts (consider springback in bending and cracking in deep drawing); thick plates are mostly welded structures (consider heat input and sensitization).
Common Issues
Which stainless steel is used most in textiles?
Based on the total of these 7 components, the most common grade is 316L (7 matches), followed by 304 (3 matches) and 321 (1 match). The specific choice for a given part still depends on the medium and temperature; for example, stainless steel worktops in contact with salt water should be switched from 304 to 316L.
Which type of component is most prone to problems?
Failure description, typically the "J-type high-temperature high-speed dyeing machine cylinder": chloride SCC: the dye contains Cl⁻, far exceeding the critical SCC temperature for austenitic grades of approximately 60 °C at 140 °C; cracks initiate at welds/fins/HAZ; recommended grades 316L/304/321, wall thickness approx. 4 mm. Such conditions suggest specifying the medium concentration, temperature and cleaning method during the design phase.
What thickness should I choose?
The thickness range in the list is 1–400 mm. For thin plates, consider bending and surface finish; for thick plates, consider welding and structural strength. Values may vary by equipment manufacturer for the same location. Re-verify with your drawing or operating conditions.
