1. What is a stainless steel needle tube?
A stainless steel needle tube is a precision-drawn seamless tube made from medical-grade stainless steel, commonly used for producing cannulas, injection needles, and micro-needle assemblies. It provides excellent corrosion resistance, strength, and biocompatibility.

2. What materials are available for stainless steel needle tubes?
We supply stainless steel needle tubes in grades such as 304, 304L, 316, 316L, and 321, meeting ASTM A269, A270, and ISO standards. Custom grades are also available upon request.

3. What are the standard sizes and tolerances?
Outer diameters typically range from 0.3 mm to 25 mm with wall thicknesses from 0.05 mm to 2.0 mm. Tight tolerances and mirror-polished inner surfaces are available for medical and laboratory applications.

4. Are stainless steel needle tubes suitable for medical use?
Yes. Our needle tubes are made from medical-grade stainless steel with high cleanliness, smooth internal finish, and full traceability, making them suitable for medical devices and surgical instruments.

5. Can you supply customized cut lengths or surface finishes?
Absolutely. We can provide tubes cut to specific lengths, with polished, bright-annealed, or passivated finishes to meet different customer requirements.
