Stainless Steel Plates for the Textile Industry: 316L/304 Selection and 7-Part List
In the textile industry, we have identified 7 parts that use stainless steel: commonly used 316L / 304 / 321, with thicknesses 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 Rapid Dyeing Machine Cylinder | 316L/304/321 | Wall thickness approx. 4 mm | 2B/anodizing and passivation | Chloride SCC: dye liquor contains Cl⁻, far exceeding the critical SCC temperature of austenite of approx. 60℃ at 140℃; 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 | Cl⁻ enrichment in condensate + 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 | Dyeing agents/corrosion protection; 120 h salt spray test with no rust is a commonly accepted acceptance criterion | GB/T 3280; FZ/T 90001 series |
| Bleaching Machine Bleaching Tank/Alkaline Solution Tank | 316L | 2.0–6.0 mm | 2B/pickling | Chlorine bleaching + stress corrosion at high pH | 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/Metering Pumps | 316L | Turned parts/Plate 5–30 mm | Finished surface/wet polishing | High-temperature polymer degradation + corrosion | GB/T 3280; GB/T 1220 |
| Wet Needle/Fabric | 304/316L | 1.0–3.0 mm | 2B/perforation | High-pressure water washing + fiber abrasion + corrosion | GB/T 3280 |

Consider Application Specifics
- Which grades are most commonly used in this industry? (316L, 304, 321)
- Typical corrosion sources: pitting and crevice corrosion (5/7 hits).
- Welded components require attention to sensitization and chloride-induced stress corrosion (3/7 hits).
- Thickness range 1–400 mm: thin plates are mainly formed parts (consider springback in bending and cracking in deep drawing), thick plates are mainly welded structures (consider heat input and sensitization).
Typical Issues
Which stainless steel is most commonly used in the textile industry?
Based on the total of these 7 components, the most frequently occurring grade is 316L (7 hits), followed by 304 (3 hits) and 321 (1 hit). The specific selection of parts still depends on the medium and temperature; for example, stainless steel surfaces in contact with brine should be changed from 304 to 316L.
Which component type is most prone to problems?
Failure description, typically "J-Type High-Temperature High-Speed Dyeing Machine Cylinder": chloride SCC: dye contains Cl⁻, far exceeding the critical SCC temperature of austenite of approx. 60°C at 140°C; cracks form in weld/flap/HAZ zones; recommended grades 316L/304/321, wall thickness approx. 4 mm. Such conditions suggest defining the medium concentration, temperature and cleaning method at the design stage.
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. Verify again based on the drawing or operating conditions.
