This product is a precision capillary stainless steel tubing manufactured from AISI 316 austenitic stainless steel. It is designed for applications requiring extremely small diameters, high dimensional accuracy, and excellent corrosion resistance. Thanks to its molybdenum content, 316 stainless steel offers superior resistance to pitting and crevice corrosion, making it especially suitable for medical and pharmaceutical environments.
Outer Diameter (OD): 0.3 mm – 6.0 mm
Wall Thickness (WT): 0.05 mm – 1.0 mm
Length: Fixed length or coil length as required
Manufacturing Process: Cold drawn, precision annealed
Surface Finish: Bright annealed (BA), pickled, or polished
Straightness & Roundness: High-precision medical-grade tolerance
Ultra-small diameter with consistent wall thickness
Excellent corrosion resistance in saline and biological environments
Smooth internal surface suitable for fluid transfer and injection
High cleanliness, easy to sterilize
Good formability for bending and micro-fabrication
Biocompatibility assurance: Medical customers are highly concerned about material safety. 316 stainless steel is widely recognized for its biocompatibility and suitability for medical devices and implants.
Dimensional precision: Small diameter tubing often faces issues of ovality and wall inconsistency. Our advanced cold-drawing and inspection processes ensure tight tolerances and repeatable accuracy.
Surface quality control: Medical users prioritize internal smoothness to avoid contamination and fluid resistance. We provide controlled surface roughness and optional electropolishing.
Clean manufacturing environment: Tubes are produced and packaged under strict cleanliness standards to reduce the risk of particulate contamination.
Stable supply and customization: Flexible production capability supports customized sizes, lengths, and surface finishes for different medical applications.
