Stainless Steel Plates for Textile Industry: 316L/304 Selection and 7 Part Lists
In the textile industry, we have identified 7 parts that use stainless steel: commonly 316L / 304 / 321, with thickness ranging from 1–400 mm.
7 parts and selection list
| Part / Component | Recommended Grade | Size / Thickness | Surface | Main Failure Modes | Reference Standards |
|---|---|---|---|---|---|
| J-type high-temperature and high-speed dyeing machine cylinder | 316L/304/321 | Wall thickness approx. 4 mm | 2B/acid pickling passivation | Chloride SCC: the dye contains Cl⁻; at over 140℃ this far exceeds the critical temperature for austenitic SCC of about 60℃; cracks initiate from welds/flanges/HAZ | GB/T 3280; GB/T 150; GB/T 4334 |
| Cylinder heat exchanger tubes/welds | 316L | Tube wall 1.0–2.0 mm | Pickling/brightening | Steam condensate chloride enrichment + residual welding stress → weld SCC | GB/T 151; GB/T 4334 |
| Guide rolls (core shaft/roll surface) | 304/316L | Roll surface φ100–400 mm; wall thickness 2–6 mm | Mirror/HL | Dye + auxiliaries + acid-base corrosion; 120 h salt spray rust-free is a common acceptance criterion | GB/T 3280; FZ/T 90001 series |
| Whitening tank/bleaching machine alkali liquid tank | 316L | 2.0–6.0 mm | 2B/pickling | Chlorine bleaching corrosion + high-concentration alkali stress corrosion | GB/T 3280 |
| Casting tank/piping | 316L/904L | 2.0–6.0 mm | 2B/pickling | Sulfuric acid/sodium thiocyanate + high temperature + Cl⁻ | GB/T 3280; ASTM A240 |
| Spinning box/metering pumps | 316L | Forged parts/plate 5–30 mm | Surface/mirror finish | Degradation and wear of high-temperature polymers + | GB/T 3280; GB/T 1220 |
| Welding head/netting | 304/316L | 1.0–3.0 mm | 2B/perforated | Water jet brushing + fiber wear + corrosion | GB/T 3280 |

Material Selection
- What are the most common grades in this industry? (Click for quotes and stock levels)
- Corrosion from chloride ions and salts is the most common source (5/7 hits).
- Welded components need attention to sensitization and chloride ion stress corrosion cracking (3/7 hits).
- Thickness range 1–400 mm: thin plates are mostly formed parts (consider bending springback and deep drawing cracks); thick plates are mostly welded structures (consider heat input and sensitization).
Common Issues
Which stainless steel is used most in the textile industry?
Based on these 7 components, 316L (7 hits) and 304 (3 hits) appear most frequently. The specific part still depends on the medium and temperature—for example, stainless countertops that contact salt water should switch from 304 to 316L.
Which type of part is the hardest to manage?
Failure description, typically "J-type high-temperature high-speed dyeing machine cylinder": chloride SCC—the dye contains Cl⁻, and at 140℃ it far exceeds the austenitic SCC critical temperature of about 60℃; cracks originate from welds/flanges/HAZ; recommended grades 316L/304/321, thickness around 4 mm. For this type of condition, we recommend specifying medium concentration, temperature, and cleaning method during the design phase.
What thickness should I select?
The thickness range in the list is 1–400 mm. For thin plates, consider bending and surface finish; for thick plates, welding and structural strength. Values may vary by manufacturer for the same part depending on your drawing or operating conditions. Recheck as needed.
