Stainless Steel Plates for the Textile Industry: 316L/304 Selection and 7 Sub-Lists
In the textile industry, we have organized 7 stainless steel component categories: commonly used 316L / 304 / 321, with thicknesses from 1–400 mm.
List of Seven Components and Material Options
| Part / Component | Recommended Grade | Size / Thickness | Surface | Main Failure Modes | Reference Standards |
|---|---|---|---|---|---|
| J-Type High-Temperature High-Speed Dyeing Machine Cylinder | 316L/304/321 | Wall thickness approx. 4 mm | 2B/anodizing and passivation | Chloride SCC: acidic solution contains Cl⁻, far above the austenitic SCC critical temperature of approx. 60 °C at 140 °C; cracks initiate from welds/flanges/HAZ | GB/T 3280; GB/T 150; GB/T 4334 |
| Cylinder heat exchanger tube bundle/welds | 316L | Tube wall thickness 1.0–2.0 mm | Pickling/polishing | Condensate Cl⁻ enrichment + residual weld stress → SCC at welds | GB/T 151; GB/T 4334 |
| Guide roll (core shaft/roll surface) | 304/316L | Roll surface φ100–400 mm; wall thickness 2–6 mm | Mirror polishing/hard chrome plating | Dyes/corrosion resistance; 120 h salt spray test without rust is a common acceptance threshold | GB/T 3280; FZ/T 90001 series |
| Bleaching tank/bleaching machine alkaline solution tank | 316L | 2.0–6.0 mm | 2B/Pickling | Chlorine bleaching + high pH stress corrosion | GB/T 3280 |
| Casting tanks/piping | 316L/904L | 2.0–6.0 mm | 2B/Pickling | Sulfuric acid/sodium thiocyanate + high temperature + Cl⁻ | GB/T 3280; ASTM A240 |
| Spinning box/feed pumps | 316L | Forged parts/plate 5–30 mm | Machined surface/spot polishing | High-polymer material degradation + corrosion | GB/T 3280; GB/T 1220 |
| Wet needle/fiber path | 304/316L | 1.0–3.0 mm | 2B/Perforation | High-pressure water washing + fiber wear + corrosion | GB/T 3280 |

Consider Application-Specific Details
- What are the most common grades in this industry? (316L, 304, 321)
- Common corrosion sources: pitting and crevice corrosion (5/7 hits).
- Welded components must watch for sensitization and chloride-induced stress corrosion cracking (3/7 hits).
- Thickness range 1–400 mm: thin plate is mostly formed parts (consider bending springback and deep-drawing cracks), thick plate is mostly welded structures (consider heat input and sensitization).
Common Issues
Which stainless steel is used most in textiles?
Based on the sum of these 7 components, the most common grade is 316L (7 hits), followed by 304 (3 hits) and 321 (1 hit). For a specific part, it still depends on the medium and temperature; for example, stainless steel countertops in contact with salt water should switch from 304 to 316L.
Which type of component is most prone to problems?
Failure description, typically "J-Type High-Temperature High-Speed Dyeing Machine Cylinder": Chloride SCC: dye contains Cl⁻, far above the austenitic SCC critical temperature of approx. 60 °C at 140 °C; cracks initiate from welds/flanges/HAZ areas; Recommended grades 316L/304/321, wall thickness approx. 4 mm. Such conditions indicate that medium concentration, temperature and cleaning method should be specified 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, welding and structural strength. Values may vary between equipment manufacturers for the same location. Double-check with your drawing or operating conditions.
