Buyer Decision Summary
| Choose This Tube If |
Your design requires a fixed 14mm outside diameter, a 0.4-2.0mm wall, controlled surface quality and optional secondary processing. |
| Best Grade Choice |
201 for cost-sensitive indoor use; 304 for general fabrication; 316 for coastal, humid or more corrosive environments. |
| Recommended Trial |
Request sample confirmation when the tube must be bent, coiled, flared or matched with another component. |
| Order Starting Point |
Normally 300kg per size and wall thickness; 316 production normally requires 3 metric tons per specification. |
| Typical Lead Time |
About 7-15 days for regular production and 15-25 days for customized processing, subject to final specification and production schedule. |

Choose the Right Grade
AISI 201
Cost-effective for indoor decorative and general-purpose components where the service environment is controlled.
AISI 304
The standard choice for general fabrication, equipment, furniture, food-related structures and wider corrosion resistance.
AISI 316
Recommended for coastal, humid, chemical or more corrosive service conditions, subject to project requirements.
Wall Thickness Selection Guide
| Wall Range |
Approx. ID |
Purchasing Consideration |
| 0.4-0.6mm |
13.2-12.8mm |
Lightweight parts, covers and applications where lower weight and easier forming are priorities. |
| 0.7-1.2mm |
12.6-11.6mm |
Balanced strength and fabrication performance for general components and equipment. |
| 1.5-2.0mm |
11.0-10.0mm |
Higher rigidity, stronger connections and machined or load-bearing component requirements. |
Final wall thickness should be selected according to loading, forming radius, welding method, tolerance and applicable project standard.
Processing & Customization
The 14mm tube can be processed for finished or semi-finished components. Feasibility is confirmed according to material grade, wall thickness, bend radius, final tolerance and application.
- Precision cutting to required length
- Bending and coiling trials before mass production
- End flaring, chamfering and deburring
- Drilling, slotting and laser cutting
- Welding, polishing and surface finishing
- Protective film, individual sleeves and customized labels
