ISO9626 SUS304 SUS316L , Stainless Steel Needle Tube , Medical Injection Needle Application
Product Description:
Stainless Steel Needle Tube is a small-bore, cold drawn needle tube which is made from 304 or 316L stainless steel due to their excellent corrosion resistance,strength, and biocompatibility. This needle tube is widely used in the medical device, aerospace, automobile, jewelry, food processing industries and so on. It is also popular for model makers. The needle tubes are produced from stainless steel strips. Stainless steel strips are processed by laser thermal fusion welding into capillary tubes, and these tubes are processed by reducing the diameter & thickness, annealing, cleaning, straightening and cutting. Then tubes are grinded into needle tubes with different needle points. This process holds tight tolerances on OD and ID. It is commonly referred to as Needle Tube. SUS304 and SUS316L needle tubes, compliant with ISO 9626 standard, ensure safety, precision, and reliability in medical injections.
YUHONG GROUP is an quality-oriented and ISO13485-certified manufacturer and supplier of medical-grade stainless steel needle tubes and capillary tubes. There are a variety of medical needle tubes that we can provide, such as injection needle, hypodermic needle, insulin needle, dental needle, blood lancet, biopsy needle, mesotherapy needle, detaining needle, back-eye needle and so on. According to clients' drawings, we can customize different stainless steel needle tubes for them.
Different Grades Have Different Medical Applications:
SUS304: Single-use needles (e.g. syringes, cannula, catheter) where cost is critical.
SUS316L: Implantable devices, surgical tools, and environments requiring frequent sterilization.

Yes, we can not only provide finished needle tubes, but also provide straight or coiled capillary tubes. The common length is 2 meter per piece.
3. What sizes are available?
Sizes range from 10 to 34G. Wall Thickness can be regular wall, thin wall, extra-thin wall, ultra-thin wall.
4.Can needle tubes be customized?
Yes, custom lengths, diameters, and needle tips(bevelled, blunt, quincke, back eye, back cut...).
5.What grades of stainless steel are commonly used?
Grades 304, 304Ni8.5, 304Ni9, and 316 (medical-grade for enhanced corrosion resistance). If the needle tube has smaller, thinner size, thus it need to choose the stainless steel with higher Ni content.
