Stainless Steel Plates for the Textile Industry: 316L/304 Selection and a 7-Part List
In the textile industry, we have compiled 7 parts that use stainless steel: commonly used 316L / 304 / 321, with thickness ranging from 1–400 mm.
Seven-part list and material options
| Part / Component | Recommended Grade | Size / Thickness | Surface | Main Failure Modes | Reference Standards |
|---|---|---|---|---|---|
| J-Type High-Temperature High-Speed Dyeing Machine Roller | 316L/304/321 | Wall Thickness Approx. 4 mm | 2B/Anodizing and Passivation | Chloride SCC: the dye liquor contains Cl⁻; at 140℃ this far exceeds the critical temperature for austenitic SCC of about 60℃; cracks originate from welds/flanges/HAZ | GB/T 3280; GB/T 150; GB/T 4334 |
| Roller Heat Exchanger Tube Bundle/Welds | 316L | Tube Wall Thickness 1.0–2.0 mm | Pickling/Polishing | Condensate Cl⁻ enrichment + residual welding stress → SCC at welds | GB/T 151; GB/T 4334 |
| Guide Roller (Core Shaft/Roller Surface) | 304/316L | Roller Surface φ100–400 mm; Wall Thickness 2–6 mm | Mirror Finish/Hard Chrome | Dyes/Corrosion Inhibitors; 120-hour salt spray test passes without rust, a commonly accepted criterion | GB/T 3280; FZ/T 90001 series |
| Bleaching Tank/Bleaching Machine Alkali 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 |
| Spin Box/Metering Pumps | 316L | Forged Parts/Plate 5–30 mm | Machined Surface/Running-in Polish | High-temperature polymer degradation + corrosion | GB/T 3280; GB/T 1220 |
| Wet Needle/Fabric Web | 304/316L | 1.0–3.0 mm | 2B/Perforation | High-pressure water washing + fiber abrasion + corrosion | GB/T 3280 |

Consider application characteristics
- What are the most common grades in this industry? (316L, 304, 321)
- Common corrosion sources: pitting and crevice corrosion (5/7 hits).
- Welded components should be watched for sensitization and chloride-induced 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 Questions
Which stainless steel is most used in textiles?
Across these 7 components combined, the most common grade is 316L (7 hits), followed by 304 (3 hits) and 321 (1 hit). Selection for a specific part still depends on environment and temperature; for example, stainless workbenches in contact with salt water should move from 304 to 316L.
Which component type is most prone to problems?
The failure description, typically the "J-type high-temperature high-speed dyeing machine roller": Chloride SCC: the dye contains Cl⁻; at 140°C this far exceeds the critical temperature for austenitic SCC of about 60°C; cracks originate from welds/fins/HAZ zones; recommended grades 316L/304/321, wall thickness approx. 4 mm. Such conditions require specifying the medium concentration, temperature and cleaning method at the design stage.
Which thickness should I choose?
The thickness range in the list is 1–400 mm. For thin plates, consider bending and surface quality; for thick plates, consider welding and structural strength. Values may vary by equipment manufacturer for the same location. Recheck against your drawing or operating conditions.
